I'd be willing to trade some really cool stuff for a US Scott #63. I have a pile of world wide stuff both mint and used and/or some other classic American stuff eg. banknotes and civil war era covers (like a #114 & 65) and maybe some other stuff if need be. Get in touch with me if you have one to move. OR..or even if you just have one to sell. MUST be a sound example. Thank you -Jay
