Great thread,
Finale Fireworker :)
So after collecting them for a bit as a teenager from 1999-2000 or so, I fell off the bandwagon for several years. Then, from around 2007-2009 or so, I got addicted to buying Japanese cards on eBay. Mainly promos, some holos and the like. Over the past few years I've bought a few bits here and there (looks like the Munch "scream" set was a good investment a couple of years ago!), but the majority I've been sat on for years and years.
I read what you said about Japanese cards with interest, and whilst I know nothing about the value of English cards, I know for a fact that several cards I have go for hundreds or thousands, as I've done sold listing searches on eBay over the past few months. Some examples of what I have...
Complete
Masaki promo set (including the pass card)
Complete
ANA Airways promo set (including the gold boarding passes)
Southern/Rainbow/Tropical Islands sets
Most of the
/PLAY promo set (going by memory, only missing Umbreon & Espeon)
A lot of the
CoroCoro promos (some sealed...I would guess Shining Mew is the most valuable there; beautiful card!)
Grand Party (1999 promo, from memory, pretty sought after)
Neo promo folders (3 of them, not sure if there was a 4th?)
Complete
Neo Genesis/Discovery/Revelation/Destiny sets (including some, but not all, of the Shining cards for the latter)
Crystal Charizard (standard holo, first edition, from the Skyridge set I think...?)
...and so many more. Here's a pic of 3 of my faves which I've just dug out;
Magikarp, Porygon and
Eevee Fan Club promos...
I
know I'm sitting on a small fortune. I would only buy NM/M/sealed cards, so I really need to take time to go through and catalogue everything I have, decide what I want to get graded, and go from there. If and when I do this, I'll keep this thread updated!
A general question for you: From experience, what's more valuable...a still sealed card, or a PSA 10? I have many cards which are still sealed or uncut. Presumably, if I were to "release" them I could get a grade 10 for them as they would be mint condition...getting ahead of myself here though. I need to find out what I have!
