1959 Ryukyu Islands revenue stamp Don
Thanks Don,no wonder I couldn't find it Brian
Brian, the Scott US Specialized catalog lists the Ryukyu revenue stamps. (The regular volume 1 does not.) It looks like yours is R18, issued in 1959, with a 2017 mint nh cv of $3.00.
I had totally forgot I do have a copy of 1997 Scott's Specialized Catalogue ,I just got it out first time in years !!I didn't think to check it ,mind you I didn't have any idea what country it was from . Brian
Great! Glad that fired a connection! But you're right, this one was tricky.
