Although I am in general agreement I feel I hould make a small suggestion...
I collected 80% of the
State Quarters when I was in the US... the trouble was that the last few years hadn't been released and I had a few gaps (and since I never collected
US coins before I visited the US I was unaware of the different mint marks so just got one for each state)
Anyway I felt compelled to fill in my gaps from
ebay and was surprised that I was charged such a premium for the ones I needed. So if you can be bothered there probably is a market there to post these abroad (mine arrived in a padded bag in a roll to order I think $12.50 for $2.50 face with a couple of bucks for 1st class international shipping)
I dont have all the national parks, territories and
ATB Quarters either, it would be nice to have all those if I could find them priced reasonably (thats one for the future I guess)
Anyway... if you can be bothered you would be doing the world a favour and it may return a little more than face.
