Since there are no other sold listings to compare with, as far as I can see, and only two more are up for sale, for 100+, It’s hard to say if what you bought it for is what the market is willing to pay or if you made a really good deal. Id recommend keeping an Eye out for other auctions and listings for this kind of card, in psa 10, and see if and what it sells for, will give you a better answer on the cards value as far as the market is concerned
I would say you got a good price but i wouldnt class it as a great buy tbh, the one syuju has listed for $120 has sat for ages at this point so its probably about market value tbh.
It looks like you’re really happy with the card and the price you got it for, based on that I would say for you it’s a great buy. But as woolsluk points out, the price itself maybe isn’t market shattering.
Yes it is very difficult to get a 10 on the English version of this holo, 100% impossible actually, which is why I prefer it over this Japanese version. :^)
