One per Customer and only for the following cards! One 2019, 2018 or 2017 Topps Black serial to 67 that I need (must provide me with number of card before the trade!) or two gold cards (2019, 2018 or 2017) that I need and again must provide me with the number so that am sure I need it. Best regards, David PS No PM's and no I'm not going to take updates or twins cards (unless the twin card is gold or black that I need)...won't be giving out a wantlist as that would be a pain for me! Right from my personal collection....don't worry...I still have about 12 lefted over!!
