Is it U71?
Do the heavy cancellations make it worthless?
Bust points between second and third notches of inner oval.. check
"G" of "POSTAGE" has a bar.. check
ear indicated by one heavy line .. ??
one vertical line at corner of mouth..check I think it is U71
The value .. that's a nice example of an ellipse cancel, so it's representive of the type. But the back shows some damage. There are lots of nice cancels on cut squares.
