How to spot a real signed Funko Pop

A signed Pop can be the star of a shelf, and autographs are also one of the most-faked things in collecting. Here's how to tell a signature you can trust from one you can't, in about five minutes.

1Who signed it?Know the signer and when they did signings.
2Who checked it?A recognized authenticator's sticker and cert number.
3Does it match?Look the number up yourself and compare the details.

The three kinds of proof

No single thing proves a signature is real. The more of these you have, the better:

How to check a certificate in 4 steps

  1. Find the number. It's on the authenticator's sticker on the box, and on the certificate or card that comes with it. The two should match.
  2. Go to the authenticator's website yourself. Type the address in your browser rather than following a link from a listing or message. Use JSA's site (spenceloa.com), Beckett Authentication (beckett.com) or PSA (psacard.com).
  3. Enter the number exactly as printed, letters included, on the verification page.
  4. Compare the record with the Pop in front of you: the signer's name, the type of item, any inscription (like a character name) and where the signature is. PSA warns that real cert numbers can turn up on fake labels, so a number that exists isn't enough. The details have to match.

Red flags vs good signs

🚩 Red flag✅ Good sign
A “COA” from the seller themselves, or from a company you can't find or look upA numbered sticker from JSA, Beckett or PSA/DNA that you can look up
“Comes with COA” but no certificate number shown or sharedClear photos of the sticker, with the number readable
The cert record describes a different signer or itemThe record matches the signer, the item and the inscription
The same signature, identical in every detail, across many listings (a sign of printing or stamping)Natural variation: real signatures differ a little every time
Stock photos only, no photos of the actual box and signaturePhotos of the actual item from several angles
A signed exclusive far cheaper than other signed copies of the same PopA seller with a long history and buyer protection on the sale
A signer who has never done signings, or a Pop released after the signer could have signed itA known signing event, convention or private signing you can find

Where signatures usually go

Most signed Pops are signed on the box, often across the front window or on a side panel, usually in paint pen or permanent marker. Some are signed on the figure itself, often on the head or the base. Wherever it is, signatures can fade in sunlight, so keep signed Pops out of direct light, ideally in a UV-protective case.

Track your signed Pops in PopArchive

Open a Pop, tap Edit and fill in the optional Signed by field. Signed Pops get a ✍ SIGNED chip and show up together under Shelves → Signed Pops, with current eBay listings for signed copies of the same Pop. It's on the free Collector Account and the Curator Account.

Tip: add the authenticator and certificate number to the Pop's comments, so they're on hand if you ever sell it or need to check it again.

Common questions

Does a certificate of authenticity prove a signed Funko Pop is real?

Only if it comes from a recognized authenticator and checks out. Look up the certificate number on the authenticator's own website and make sure the record matches the signer, the item and the sticker on the box. A seller's own certificate, or one from a company you can't look up, proves very little.

Which autograph authenticators do collectors trust?

The names collectors mention most are JSA (James Spence Authentication), Beckett Authentication Services and PSA/DNA. Each puts a numbered sticker or label on the item and keeps a record you can look up online.

How do I verify a JSA, Beckett or PSA certificate?

Type the authenticator's website address yourself (don't follow a link from the listing), open its verification page and enter the certificate number exactly as printed. Then check that the record describes the same signer and item. A matching record shows the number exists. Fake labels can reuse real numbers, so the details have to match too.
