Found this stamp in a greens mixture of about 1000 stamps that was all over the place with duplications and condition. this stamp and a few of $1 to $5 dollar cat. and a cut cancel RD260 with serial # 7015 greens all used for $20.
The R338 has a 3 wavey line cut cancel and what I think is a low serial number of 10. Were many sold? just wondering if it is a low serial number. Anyplace to research that type of information?
thanks for your time and assistance.
