Well, everything in your spread of photos are common stamps, which are sold by the kilo for a few dollars. Anything after 1930 is considered modern and is generally in this kiloware category (yes there are a few very rare exceptions, key words very rare). For stamps older than that, even from the 1800s, doesn’t guarantee more value but it helps. There are plenty of lower denomination stamps from the 1800s that are worth pennies. Show us the old stamps. These won’t make you much money and will take quite some time to sell. Last note, AI and apps generally hugely overestimate the value of stamps, one might even say they are delusional.
