I have a 3 centavo, Follansbee # 212 , that has a very clear postmark that I can't identify. The cancel style is different from any major type in Shimmer. It is an double oval cancel similar to Shimmer type O3 but with a narrow line thru the middle of the oval. The town name is ..scacueso, possinlt .uscacueso. I have been thru the Shimmer index and can find no towns wvwn close to this spelling. Any ideas?
