Oh hey, I have one of those hideous green-flip CGC cards. I traded a PSA 10 1st Bowman Chrome Acuna and a PSA 9 Topps Holiday Ohtani rc for it about 2 years ago.
Its been in my trade/sell case for over a year and hardly anyone even asks how much I want for it lol.
If I wasn't so opposed to mailing cards across the country I'd have them re-holder it with the new look and probably sell it within a couple weeks.
