This may seem confusing but it's pretty simple.  I'm willing to pay well over market price for any very very old card in your collection. This is how to do it:

First: Go to your collection, and sort your collection by date ascending, and find your oldest Non-cr card. (it should be the first non-cr at the top of your collection)

Second: find your card number (if you scroll over the card it should show you the card number) write down that exact number. 

Third: send me a PM with the card name and that exact card number for that spesific card.  
If it is a VERY low number I will be willing to pay well over whatever the market value is for that card. 

Lastly: enjoy your clintz.

Again, to be clear, I am only looking for extremely old non-cr cards. 
Thanks
