Original or reproduction?

These are live eBay listings, so "1921" in a title can mean two things: a jersey made in 1921, or a throwback printed last month. The first thing to check is the maker's tag against who was actually making jerseys then.

  • A Mitchell & Ness or Hardwood Classics tag means a licensed reproduction. A fine gift, not a 1921 original.
  • Ask the seller for photos of the neck tag and the wash tag. Logos, fonts and fabric should match the era.
  • The tag check has a limit: counterfeits copy the correct maker tag too. Price is the signal that scales. Real vintage doesn't sell far below every comparable listing, and a game-worn jersey priced like a t-shirt is neither.
  • The Era originals filter above hides listings that are newly made by their own description: multi-size runs, custom name and number offers, reproduction brands. What survives isn't guaranteed original. A one-off fake in a single size with the right tag passes every check a listing allows, which is exactly why seller photos and feedback still matter.
