Thats a sweet card but IMO you wont get 500US. If you think about it you can get a jordan auto for 400 US and personally I woudn't get a non auto (even a patch) for more than an auto card. But thats my opinion and I haven't looked through ebay yet for market prices.
if the card mavs just posted only went for 485usd..
there is noway the card you have would go for 500 if that didnt...
this is because
the one on the bay is a patch from his chicago uniform
the patch looks like it is from his name on the back of the jersey
its from ultimate collection
its numbered to 25
its a much larger patch
i would expect to get around say 250usd for that card
