Types of Football Helmets: Speed, SpeedFlex, Authentic, Replica and the Alternates

Walk into a card show or scroll a memorabilia site and you'll see a dozen words attached to the word "helmet." Speed. SpeedFlex. Authentic. Replica. Lunar. Salute to Service. Mini. Some of those describe the shape of the shell. Some describe how it's built. Some are just a paint job. They all change the price.

We handle more signed football helmets than anything else we sell, so here's the plain-English breakdown of every type you'll run into, what it costs, and which ones collectors actually want signed.

The short version

• Shell style is the shape: Riddell Speed, SpeedFlex, Axiom, or a throwback like the VSR4.
• Authentic vs replica is the build: real on-field construction and padding, or a lighter display version that looks the same from the shelf.
• Full-size vs mini is the scale. A mini is about half size and sits on a desk.
• Alternates like Lunar Eclipse, Eclipse, Flash, Slate, Camo, AMP and Salute to Service are special finishes on the same shells.

Any one helmet is a combination of those. A "Chiefs Speed Authentic Lunar full-size" is a Speed shell, built authentic, in the Lunar Eclipse finish, at full scale. Once you can read that string, you can read any listing in the hobby.

Shell styles: what the players actually wear

Riddell has been the dominant name in football helmets for decades, and it held the official NFL helmet deal from 1989 through the 2013 season. That's why nearly every signed helmet you'll see is a Riddell. Here are the shells that matter.

Riddell Speed. Introduced in 2008 and still the most common shell in the hobby. It's the classic modern look: clean lines, a slightly extended jaw, and the shape most people picture when they think "NFL helmet." Speed shells come in an authentic full-size, a replica full-size and a mini, so the same shell shows up at every price. That's a big reason it's the default for autographs.

Riddell SpeedFlex. Came out in 2014 and you can spot it from the stands by the notch cut into the crown. That notch is a flexible panel that gives on impact. The SpeedFlex is what a large share of current NFL players wear on Sundays, and it's the premium option for collectors. Signed SpeedFlex helmets cost more than the same player on a Speed shell because the blank helmet itself costs more.

Riddell Axiom. Riddell's newest platform, launched in 2022 with a 3D printed liner version following in 2024. It's showing up on more NFL heads every season. You won't see many signed Axioms yet because the collector versions are still scarce, but that will change.

Riddell VSR4. The shell of the '90s and 2000s. Tom Brady famously stuck with his right up until the NFL took it off the approved list in 2018 and let players who already had one finish out that season. Today the VSR4 shape lives on in throwback helmets, and it's the right shell if you're getting a Hall of Famer from that era to sign.

Riddell Revolution. The 2002 helmet that started the modern era. It's mostly been replaced by the Speed and SpeedFlex, but you'll still find Revolution shells on signed pieces from the mid-2000s.

Schutt, Xenith and Vicis make helmets that NFL players wear too. You'll rarely see them signed because the teams and licensing deals push collector helmets toward Riddell. If a listing says "Schutt" or has a facemask that looks different from the rest of your shelf, that's why. Our post on the history of Riddell helmets walks through every one of these eras in order.

Authentic vs replica: how the helmet is built

This is the one that trips people up, and it's the one that moves the price the most.

An authentic (sometimes called a proline) is built like the helmet on the field. Polycarbonate shell, full interior padding, snap-in ear pads, a four-point chin strap, real weight. Pick one up and you know.

A replica looks the same on the shelf but it's built for display. Lighter shell that's about an inch smaller, foam inserts instead of real padding, a two-point chin strap on most models, smaller decals. It costs a fraction of the authentic and it takes a signature just as well.

Neither one is meant to be worn. Both come with a label saying so. We wrote a whole post on the difference between authentic and replica helmets with photos of the insides side by side, so we won't repeat all of it here.

Full-size vs mini

A full-size helmet is the real thing at real scale. It's the centerpiece of a room. It also needs a case or a stand and about a foot of shelf space.

A mini is roughly half scale, about five inches tall, with the same decals, a working chin strap and interior padding. It's the most popular item in the hobby for a reason: you can fit twenty on a bookshelf, the blanks are cheap, and a signature shows up big on the small surface. They're a staple of our live breaks, and we keep thousands of signed mini helmets in stock. If you're just getting started, that's where to start. We wrote a separate post on why minis are such a strong first buy.

Alternates: Lunar, Eclipse, Flash, Salute to Service and the rest

Every year Riddell and the NFL put out a handful of special finishes on the Speed and SpeedFlex shells. Most of these were never worn in a game. They're made for collectors, and they've become some of the most popular helmets to get signed because they stand out on a wall of team-color shells.

• Lunar Eclipse. Flat white shell, white facemask, gray-toned logos. Probably the most popular alternate right now.
• Eclipse. The opposite: flat black shell, black mask, black hardware, matte team logos.
• Flash. Team colors with a metallic flake finish that shifts in the light.
• Slate. Dark gray shell with muted team colors.
• Camo. Team colors worked into a camouflage pattern.
• AMP and Chrome. Older alternates from 2018 and 2019. Chrome is a mirror-finish shell, AMP is team colors with bright accent stripes.
• Salute to Service. The NFL's military appreciation line. Tan or camo shells with the Salute to Service ribbon, new design each season.

One thing to know before you buy an alternate to get signed: dark shells like the Eclipse and Slate need a silver or white paint pen, and white shells like the Lunar need a bold color that doesn't blend in. Our guide to pens for autographs covers which pen works on which surface.

What each type costs

Prices move with the player, the authenticator and the market, but the blank helmet sets the floor. Roughly, before anybody signs it:

• Speed mini: around $35 to $45
• Speed replica full-size: around $150 to $180
• Speed authentic full-size: around $350 to $400
• SpeedFlex authentic full-size: around $450 to $550
• Alternates: add $20 to $60 on top of the base shell

Then the signature goes on top, and that's where the real range is. A signed replica of a current starter might be a few hundred dollars. The same player on a SpeedFlex authentic with a witnessed COA can run past $1,000. A Hall of Famer or a dual-signed piece goes higher. When you're comparing two listings for the same player, check the shell type first. That's usually the whole difference.

Which type should you get signed?

Here's how we'd think about it, having shipped a lot of these.

Buy a mini if you're new, you're collecting a lot of different players, or you want a signature you can actually see from across the room without dedicating a wall to it.

Buy a replica full-size if you want the big-helmet look on a budget, or you're getting a mid-tier player signed and don't want the blank to cost more than the autograph.

Buy an authentic full-size if this is a player you'll keep forever, you care about resale, or you're a details person who's going to notice the padding and the weight every time you pick it up. Authentics hold value better, and on a marquee name they're what buyers expect.

Buy an alternate if you want the piece to pop, or the player wore that finish in a game you remember.

Whatever you pick, get it authenticated. A helmet is a big enough purchase that a witnessed COA from JSA, Beckett or PSA/DNA should be non-negotiable. Our post on what a COA is and why it matters explains what to look for.

Where to find them

We keep hundreds of authenticated signed full-size helmets and thousands of signed minis in stock, across every shell type on this list. If you'd rather take a shot at a big name for a fraction of the price, that's what our live breaks are for. And once you've got a helmet in hand, our guide on how to display signed memorabilia covers cases, stands and keeping the signature out of the sun.
