My greatest "steal of a deal" was fairly recently. About the start of Covid I bought a complete raw set of Topps 1959 Football from Touchdown Treasures. It was billed as about half NM and half Nm-Mt. I had the bulk of the set PSA graded. Many low pop 9's. Many star 9's including Jim Brown (RIP). One 10, and a multitude of 8's, 8.5's. Within a year I had a top ten set on the Registry. Completely graded at almost 8.50 GPA, and I really did not have to invest too much $$$ for upgrades. The set easily values at $35K+. Maybe even $40K.
I have less than $10K into it. Almost 4X in 3 years. One of my greatest hits in an entire lifetime of collecting. Lucky.
