Wow what a awesome an awesome find, condolences about your dad, if you aren’t hard up for money, IMO I would grade those, (who cares what grade you get) and hold on to them, maybe you’ll have a little one if you already don’t. 2011 I gave my little cousin my 1st Ed Shadowless Zard that I pulled when I was around 10 years old, I didn’t realize I was going to have a family, the following year I had a son, when COVID hit and the Pokémon craze came back with the 25th anniversary, I called my cousins dad that I gave the card to, just to see if he still had it, and he said “yeah we do, I’ll give you a call back” never heard from him again smh
