Lot includes (four) 4 blocks of 4 stamps Hong Kong 1972 Queen Elizabeth & Philip Silver Wedding Anniversary $.10 #271 and (two) 2 blocks of 4 stamps $.50 #272
Stamps were found in a postcard collection from a family of missonaries who lived in Hong Kong & China in the 1960's-1980s.  They appear to be MNH. I'm a postcard seller and not a stamp guy,  so you'll have to judge by the pictures.  The postcards that came with these stamps would lead me to believe these are authentic.  They were stored in cellophane envelopes.
