There’s a sub over on Reddit called r/askastampcollector and the only thing it ever gets used for, virtually always in fact, is people just show up with stamps that they found or inherited or they were given, looking for a big paycheck.
It doesn’t work that way and a lot of them get positively upset when they receive the news that what they have is worthless, but honestly, can we just stop worrying about value when it comes to collectibles? You people are going about it all wrong!
