If you grew up collecting baseball cards in the '80's like me, you probably weren't as familiar with dealing with the high-number scarcities prevalent in the '50s-'60s cards. High-number scarcity ended with the 1973 Topps set. Years later, collectors that didn't remember collecting in the pre-1974 era going to be as willing to pay the extravagant prices that were once demanded from sellers. Finding vintage high numbers at 5%-10% BV was relatively simple from 2000-2015, but things have changed. Topps came up with a genius idea to infuse high-number scarcity back into the modern sets in the 2000's. Now modern collectors understand the concept, and with vintage card pricing sky-rocketing these days, finding already overpriced high-numbers for under 25% BV has become tough.
Five years ago, I was hesitant to purchase 63T high-number commons for even 10% BV at $2.50 each. Good luck finding them for $5.00 today. Well, today I found a 63T #544 Rusty Staub RC for $17 + $1.19 tax = $18.19 and decided to make the move on a newly listed 'Buy it Now' auction. It's a $50 BV card, so my goal has always been to buy it for under $10. I've come close plenty of times, but Rookie Star cards from the 63T set have always come at a slight premium. I saw another Rusty Staub RC going for $10.50 with a few bidders on it and a couple of days left, so I decided not to risk it. That card ended up going for $31 plus tax and shipping. No I don't think that this card was worth 36% BV, but since I'm now only 33 cards from completing the set, every card addition really adds to the power of the set. If I can get it down to missing only the the Pete Rose RC, I think this set will become very marketable.
