Been around the hobby long enough to know this to be the case. With the recent Covid boom, I have literally witnessed hundreds of cases of people cracking 8.5-9.5 BGS graded cards to cash in on the PSA misunderstood “10’s” that I think is largely being driven by ignorance on eBay and perhaps comc to a lesser extent.
so I am very confident when I say that a BGS is typically 0.5 to 1 lower for equivalence to PSA. But for some unknown reason, newbies to the hobbie are throwing around huge amounts of money without realizing this. People are going to get burned here I think
I've been collecting for 20 years. Pre-pandemic PSA 10s were still outselling BGS 9.5s. I also posted the historic gem rates on the other page, but I'll include them on this post. It's been historically easier to get BGS 9.5s than PSA 10s. I'll trust the data more than anecdotal evidence.
All-Time Gem Rates (PSA 10 or BGS 9.5+) as of January 1, 2022:
2020s: PSA 58.7%; BGS 68%
2010s: PSA 55.1%; BGS 64.7%
2000s: PSA 36.4%; BGS 37.1%
