BHUTAN 5 FIRST DAY COVERS ALL UNCANCELED WITH CORRECT AND INCORRECT POSTAGE

Description

This is a lot of 5 BHUTAN FIRST DAY COVER STAMPED ENVELOPES.
They are uncanceled and not postally used
The source was BHUTAN-INDIA where there is a brisk commercial trade in BHUTAN stamps and postally used covers.
Some of these covers are UNCANCELED FIRST DAY COVERS with postage stamps which match the first day covers.
IT IS VERY HARD TO FIND THIS VARIETY OF BHUTAN FIRST DAY COVER!
In this lot, I believe 2 uncanceled covers are such, i.e., postally correct examples.
Other covers may have incorrect postage for the particular cover.
Please check the scans.
Mailing in the U.S.A. is .65.
