So, this isn't actually a hockey jersey, but related to eBay ripoffs and people not doing research.
A quick background, Zico was a Brazilian soccer player who many would rank in the top 5 of all time. In 1982 he moved to then-small Italian team Udinese and had a sensational 1982-83 season. The shirt Udinese wore that year was made by a tiny South American company called Americanino, who definitely never made shirts for any other European teams. This shirt is impossibly rare and also in high demand because of its association with Zico. I've looked on eBay regularly for it, as well as the rest of the web, and while other 80s soccer shirts do show up, I can say with a fair degree of certainty than an authentic RETAIL version of this shirt has probably never appeared online in the last 7-8 years, never mind a game-worn. Now one claiming to be a game-worn Zico pops up on eBay:
It so happens that I have this shirt; the real thing. My grandfather bought it when he went back to Italy to visit family that year and gave it to me for my birthday some years ago. Since I realized the significance of it I've treated it like gold.
Now, this shirt looks quite similar to the real thing, but the first and very obvious reason I'm skeptical is that this shirt is perfectly white, the stitching is all still pristine, there are no pulls or bobbles and the Udinese badge is still perfectly smooth. Seriously, there's no way a polyester wool shirt like that stays perfect for 30 years, and there are no signs of match wear at all, which again is impossible for a shirt that would have been worn for at least a few matches in a row, if not for the whole season (along with one short sleeve shirt- the shirt-trading thing between players hadn't started yet). Secondly, there appears to be some sort of a backing, or at least a different stitch pattern, behind the AGFACOLOR sponsor. Not the case on my original. The 'udinese calcio' lettering also looks far too perfect for a shirt of that age, and instead of connecting letter-to-letter as they do on my shirt, the stitches connect to the black strip below. Also, the yellow part appears to be stitched above the rest of the badge, which is again not the case on my shirt.
What one DOES see a lot on eBay are very accurate (and readily available) recent reproductions of this shirt- all of which were made with Zico's no. 10 on the back- deliberately mis-represented as originals. What seals it for me is that this shirt started at only 15 euros- an actual Zico 1982-83 game-worn shirt would be worth thousands. It's not the first repro claiming to be game-worn I've seen either, and of course it's always no. 10 Zico, never Causio or Virdis for example, who were also great and popular players.
This same seller also claims to have Marco Van Basten's Milan shirt from the 1990 European Champions' Cup final on sale, a completely ludicrous claim, which is currently getting only at about 120 euros with 2 days left; if THAT was what he claimed it to be it would be worth an absolutely astronomical amount. Now some naive tool is going to go around telling everyone he has Zico's Udinese shirt, but I suppose if someone can't tell the difference between a brand new shirt and a 30 year-old one... If it looks too good to be true then there's a 99% chance it is.
