Thanks for stopping by, and for honoring me with such a thoughtful first comment on Hive! Welcome to the community!
Most stuff we collect is worthless. Just in stamps, just the fact that something is really old means nothing. A stamp that was used on millions of letters in 1875 is just an OLD common stamp. You can buy an entire chest freezer full of wheat pennies for $1000... it'll contain 100,000 pennies, give or take.
The great "success" of my 50-odd years of stamp collecting is that on a "net" basis, it has been 99% self-funding. And I'm pretty stoked about that! Maybe there'll be something good in the new bins... who knows? It'll be fun to look.
