I have 61, 2008 Topps Moments and Milestones Gary Seffield printing plates. I don't really find them all that rare considering there's a bunch of them. There's only two on eBay currently that sold for $15 and $10. I'd love to get $15 a piece for them but I'd prefer to sell a lot of them. Or should a player collector hold on to something such a these? There's just something like the Moments and Milestones set that a printing plate just doesn't attract me and I'd rather have the extra cash. Any suggestions? Thanks
