Take a look at this completed auction for a 2010 Topps Tribute Cano "Patch"
This seller has over 600 cards for sale currently and they are all high end cards, autos, game used or patches. Take a look at this 2009 Topps Triple Threads Adrian Peterson Patch
Now I am not saying every card this seller has is fake. Nor am I trying to point out some negative aspect of collecting. The reason I am writing this post is that I know there are many collectors just getting back into the hobby and maybe you see one of those Cano cards of a player you like and you end up getting duped. I don't want to see that happen to anyone.
Another idea I had about this seller is that he may buy bulk lots of high end cards and not look at every single one when he buys it, however if that is the case he should notice them when he scans them. Anyone dealing with cards as a business would know that you would NEVER get a DUAL PATCH /25 like that. So even when I tried to play devil's advocate on this, the guy is still wrong. You should know better if you are running a "card store" on eBay from "Rookie Card USA".
