The images below show an accumulation of US stamps, most of which have been in glassine envelopes for the last 50 years. To my eye, untrained as I am in US stamps and even without a catalogue (My collections cover Australia, New Zealand and Canada), they seem a rather rag-tag bunch. Is there anything there that is worth something? If not, then I shall probably just give them away. The stamps in the third image are mostly mint but the gum is somewhat patchy.
I can provide a high resolution picture of any of these stamps if needed.
