I found my first non-sealed PCGS slab today
Going through some coins, I noticed one was rotated 90 degrees in the slab. When I pulled it out of the PCGS box, the coin fell out of the bottom... Is this an Ultra Rarity I can sell for $10,000 on eBay? I'm really glad it was a silver bullion coin and not anything of real value.
I will add that after all these years, I found out that PCGS slabs are NOT put together like I expected. Have they changed how the two pieces join over the years?
