Stamps (Philately)/sheet stamps


Hello Mark

I have some sheet stamps that I would like to possibly sell.

From a high to low could you give me an idea of what their value may be?

1969 ten cent airmail first man on the moon sheet of 32
1970 six cent xmas nativity pre-cancelled sheet of 50
1971 eight cent united states in space sheet of 50



All three stamp issues are common, which is the case for the majority of stamps issued in the era surrounding the 1970's.  Most sell for about face value at the online auction site  The pre-canceled nativity issue sheet may yield the best return, since that version of the stamp is slightly less common.
