Back in April 2017 a guy posted a thread called the Ultimate trade up were he wanted to start with a T205 Johnson grade VG and try to TRADE UP to a 52 Mantle. I was the guy that made the 1st trade with him. I gave him a good deal because I wanted the 1 Major HOF, more than the number of lesser T206s etc. Overtime the his effort petered out, but it was of the best treads of that year.
