Think back a few years back to July, when I busted a box of 19-20 SP Authentic. One of the cards I landed was an Inscribed Future Watch of Nick Suzuki. The first 50 stamped of the /999 print run for some of these cards add the player's debut date to their signature. It turns out those were very much in demand, and when I put it up on COMC, I turned it into about $400.00.
Since it is always easier to spend money on cards when you use proceeds from another card, I took advantage and added a some big wants to my collection.
