Well its a little past 2.5+ years, but to answer your question and re-boot, have the values really changed? You betcha. Lets take a look, with Memorex's picks for example:
Posted September 5, 2020
My pics right now would be:
Tale of suspense #39 CGC 4.0 (Go Collect $6,250) as of today Go Collect $15,500
Journey Into Mystery # 83 CGC 4.0 (Go Collect $6,250) as of today Go Collect $15,500
Hulk #1 CGC CGC 1.0 (Go Collect $5,250) no price on Go Collect but lets say $10,000
Tales to Astonish #27 CGC 6.5 (Go Collect $6,000) as of today Go Collect $18,500 but I highly doubt this FMV as there haven't been recent high grade comp sales. Lets say $10,000.
Fantastic Four #5 CGC 5.0 (Go Collect $5,500) and the winner as most others agreed, as of today Go Collect $17,500 which is probably undervalued as recent 4/20 sale was $19k.
So to answer, prices are even SKY HIGHER. Can't go wrong with blue chip keys. Secure your copy if you can.
