My aunt left two shoe boxes full of first day issues envelopes to my boy. Problem is 75% of them have her name on the envelope with a return address label she affixed when she sent it in, to have it mailed back. The rest do not have her name on them. I know stamp collecting is not a money maker but do these with her name have any value? What if we blacked out her name? Could the stamp corner be torn off and collected? When I collected as a kid in the 60's that how it was done, a cancelled stamp with the envelope paper still attached. There was literally a wheel barrow of these but my brother divided them and I think we got the biggest portion with her name on them.
