I just bought a full sheet of Edgar Allan Poe stamps from 1949 for $4.99 plus shipping. I feel like this should be worth hundreds of dollars for how old it is, who it is, the “full sheet” status… It’s 75 years old and an American icon!! What am I missing? I basically paid 1949 prices for these.

Note: it is just a coincidence that this is the second stamp post in the last 12 hours
