My favorite sports card ever...
1080 Rookie Bird/Magic with Dr. J scoring leader on one card.
A card you could find for $20 (25 years ago)...
Now, depending on condition and seller can be had for $165 to $27,000
Personally had this card along with as many Jerry Rice rookies as I could find. (they were also $20 back then, $3,500 now).
No one wanted anything but Baseball cards in the late 1980s.
I saw the value but eventually sold off all my cards to fund a trip to Vegas.
No patience back then.
