Hi,
I found this coil 2c Washington that is perforated 11 horizontally. I can only find a coil that is perforated 10 horizontally in the Scott catalog (606). I am probably missing something obvious but can someone help me identify the perf 11 stamp. The photo I included shows the p11 stamp on the left and the p10 (606) stamp on the right.
Thanks!
David
