Ahh, yes, that old attachment thing...good luck avoiding that one! Re investment, you're looking about as far in the wrong direction as it's possible to look on that front! Royal Mint coins are the weakest link in the coin investment sector! There are other far more lucrative areas, but there are no quick routes there! There is the occasional short-cut to be found within the threads on here and, equally, by your questions asked but, essentially, knowledge, intelligence and experience, as always, will be what's required! As I have said on numerous occasions, I learnt more on here in 1 year, than I ever did in 15 years of fumbling around alone! The best advice I could ever give anyone would be to spend a week surfing this forum, and then stay around for a while! Don't spend 15 years of your collecting life on your own...it's expensive and time wasting! Good luck, hopefully you're on the brink of a new-found numismatic discovery!
