I was hoping to have a second set of eyes on a couple of 3c Washington stamps I believe have double impressions.
Have a look... thanks!
01 - See area under "3" - shaded outside frame
02 - See area under "3" - can make out 3 outline below frame, see "H" of "THREE", bottom portion of stamp.
03 - See various areas in lettering (possibly not a double impression)
