What is the most valuable vintage sportscard collection worth

oh, and to the people who argue that there are many ungraded high end sets and singles in private collections....

true, there probably are. but it won't matter at all unless they come up for sale. and most collectors (i'm making an assumption here) will probably hold on to their raw collections for many years to come. if they never see the light of day, they might as well not exist. of course if these guys decide to grade their cards and flood the market, the high grade/low pop values will plummet.

i must ask: what would happen if everyone holding their E107's decided to cash in and sell? the market would become flooded (relatively, of course) and E107's would significantly decrease in price. on of the reasons those cards are so damn rare is because most are tucked away in private collections.

same with high grade/low pops
