What is a "professional model jersey"?

[r2d2]

I am asking due to a friend pointing towards this auction:
http://www.ebay.com/itm/1979-Franci...311?pt=LH_DefaultDomain_0&hash=item2801f1ac2f

He asked me if it was game used jersey and I couldn't answer him as I hadn't heard the term before. The auction doesn't mention game used at all but also doesn't mention "replica". So maybe something in between?

Thanks

It maybe a jersey made / issued for the player but most likely wasn't worn in a game.

i don't know the answer, but if it's like a minor league club, the fan jerseys at the pro shop come in a low grade one and a professional grade which rivals or matches what is worn on the field.

I bet the auction is calling it a "professional model jersey" because it is not certain if this is a high-grade fan jersey or is berrios actual game-used jersey.

google searches find lots of auction houses using the term, so it may be a CYA since there is no proof or documentation of being game-used or game-worn (so worst case, one assumes it is a high-grade fan jersey).
