Welcome to the community!
The Goldstars usually go for something between $25 (the promo ones), $35 (the ones which are less sought after) and $50-$60 (cards like Charizard, Rayquaza, etc).
I was able to buy almost all of them for $30 each. The only ones I’m missing are Jolteon, Vaporeon and Flareon from the World Championship set and Mew and Mewtwo from the gift box.
Seeing you have a few of those, what do you think about this offer:
Jolteon 1st ed
Flareon 1st ed
=$65 shipped to Germany
LMK
If you make me a good offer, I may be able to buy all of them in bulk. Consider that non-1st edition ones are worth a lot less, though.
Shoot me a PM with your offer.
Well, my offer for the whole lot would be $500 shipped. It’s up to you to accept or not 
I would price it more around $700
How about $400-500 when priced as bulk lot and $750-800 when sold individually?
No longer for sale. Thanks everybody!
As you probably all have realized I am very new to this site and sure how everything works. Now that these have been sold how do I delete the thread? I can see how to delete my own replies but not the whole thing. Is this something that admin does or does it automatically expire? Can someone shed some light? Thanks very much
Sure, if you sell everything individually or find someone who wants to keep the cards for their collection, $700 is realistic. But as I said, I’d only buy them to resell and keep the ones I need. That said, it should be clear that I’m not offering what they are worth.
