I like your airmail stamps. that pair of 6c airmail stamps looks like the most monetary value - catalog price for them is $18 each. You'll never sell them for that much - maybe 10-20% of that
Your oldest stamp is the 3c purple in your 1st image. It was printed in 1890. It catalogs for $20 as used.
Which airmail pair, the C23? I see the catalog value as 25 cents per stamp.
And the 3 cent purple #221, my 2024 Scott has that at $9.00 (in VF condition, but this one looks like the perfs cut into the design at the top, making it possibly a grade 50 if no other faults, listed at $1.75 retail catalog value).
Not to be harsh, but the monetary value of everything shown is negligible. A nice souvenir of someone's hobby, but not even worth donating to a thrift shop.
