Very fair question. Short answer is trying to optimize for cash flow. I _could_ try to hold on a few of the 10's to try to see if the value goes up and I can turn a profit, and I absolutely do that sometimes, but sometimes I just count my losses and move on so I can have the cash to put into something that I can get a higher profit on. Also sometimes it's auctions that just underwhelm. A lot less predictability there for sure.
@@everycardastory I can see that. I just dabble on ebay, if I don't get my price, or what I feel is a reasonable offer, I don't sell it. I'm not really an investor, it's just part of my hobby. I've been collecting since the early 70's.
