I would offer $350 in the dark for any Top 8 International Promo I don’t have yet (Double Colorless , Ultra Ball either year, Quick Ball, Choice Band, Pokemon Communication).
I already have EUIC Wahlband 2019, NAIC Quick Ball 2022, NAIC Ultra Ball 2017 and OCIC Double Colorless 2017. I would purchase extra copies at $150 in the dark.
Happy to negotiate and I would prefer to know the provenance of the card if possible. May pay more if you can prove which player who you bought it from.
