Everyone is talking $$$ in here. The real question is do you actually have interest in the shining set?
Based on the responses here it seems like if you ever buy anything other 1st ed charizords you’re wasting money. Should I never buy anything with less potential than a 1st ed charizord? Are people who buy Japanese shinings dumb because they could be buying more charizords instead? If you are actually genuinely interested in collecting pokemon cards, you’ll realize not every purchase - in fact most purchases - are not going to be financially optimal.
So ask yourself this. If you had an extra $6000 to spend and only one 1st ed charizord, would you rather:
- keep the money
- buy another PSA 9 1st ed charizord
- buy a Japanese shining set and keep an extra $1000
That should answer your question
