10 years and no increase in the population
I bought a PSA 9 1973 O-Pee-Chee Jim Catfish Hunter back in 2009. Ten years later and it remains a POP 1
with none higher.
Have you owned a PSA 9 card for a long time that has not seen an equal yet ? Not talking about 10's, just 9's.
How long have you had it without another 9 showing up ?
