I have a fairly large pane (not a full sheet) of Burmese 1 pie stamps from WWII with Mlty. Admn. overstamp. They come from a family member who was atttached to the RAF there during the war and are unused. How would I evaluate them monetarily?

Meaning that the stamps were given away in small packets as a free gift to entice people to ask for a selection of approvals. Such advertisements were found on match books, and magazines like "Boy's Life" and "Popular Science".
