Reselling News: eBay Makes Coin Authentication Mandatory at $500 and myFitment Shuts Down September 30

Two eBay changes this week carry a date on them, and both of them change how you pack and ship rather than what you pay. One covers coins, one covers auto parts, and both are already in motion.

eBay now authenticates coins at $500 and up, and you cannot opt out

eBay expanded Authenticity Guarantee to collectible coins on August 18 and has been ramping it up over the weeks since. Graded US coins, graded world coins, and raw US coins that sell for $500 or more now go through Professional Coin Grading Service for a multi-point inspection at no extra cost to the buyer or the seller. Sets, lots, collections, mystery products, and anything listed in the bullion category are not included.

The part sellers need to read twice is that the program is not optional. As EcommerceBytes reported, eBay told sellers the badge appears automatically on eligible listings and there is no way to turn it off. When the coin sells, it goes to eBay's authentication facility first, gets inspected inside one to two business days, and then ships on to the buyer with tracking. Coins at $1,500 and up require a signature on delivery, and you cannot combine one of these items into a package with anything else.

What that means for you: if you list coins anywhere near the $500 line, the delivery clock is now longer than your handling time suggests. Do not promise fast arrival in the listing, do not plan on bundling a high-value coin with the rest of a buyer's order, and factor the extra leg into how you describe shipping. Free authentication is a real gift for a category built on trust. It just comes with a detour.

myFitment closes September 30, and there is no export tool

If you sell auto parts on more than one marketplace, this one has a hard deadline. eBay is retiring myFitment as a standalone service on September 30, ending its support for Amazon, Rithum, SureDone, and other outside platforms. Paid subscriptions have already been cut to $0. Submission, updating, correcting, and monitoring of fitment data for those outside platforms stops on October 1.

Compatibility data that myFitment already pushed to your Amazon listings stays where it is, but nobody maintains it after the deadline. eBay is not providing a data export or a migration tool, so rebuilding the process falls entirely on the seller. The technology itself is not disappearing, it is going in-house: eBay is folding it into Fitment Plus, which applies compatibility data automatically to eligible eBay Motors Parts and Accessories listings.

What that means for you: eBay-only parts sellers are largely fine and arguably better off. Multichannel parts sellers have about four weeks to pull their fitment data down and line up a replacement with Amazon or their listing provider. Waiting until October to discover the export button is gone is the expensive version of this.

The takeaway

Both stories are the same lesson in different clothes. Platforms keep pulling services in-house, and when they do, the convenience gets better on their turf and worse everywhere else. Coins on eBay get free expert authentication that no individual seller could buy at that price. Parts sellers outside eBay lose a tool with no replacement handed to them. Read the deadline, adjust the workflow, and do it before the date instead of after it.

If you want the sourcing and listing system behind all of this rather than a headline at a time, that is what we build inside The Income Lab.
