Most of my collection as the majority was brought pre 2020!
The highlights though:
Pikachu Victory Ring in 2017 for $435 in Japan which graded a PSA 8. I found it in Mandarake and at the time I didn’t know that much about the card and was on the fence whether to buy it. Scott basically said it was a great deal so I brought it and the rest is history. You can still find that thread I made at the time here:
Unlimited base set Charizard which graded a PSA 10. Cost me about 50 pence, I brought a bulk lot of cards back in 2013 and it was in there.
1st edition base set Charizard PSA 9 - £900 back in 2016
Topsun Green back Charizard - £40 - graded a PSA 10.
It’s crazy to think what you used to be able to pick up back in the day.
