I heard somewhere that stamps are legal tender and you can use them as such (maybe on a show or in a movie; I don't remember). But I was curious to know if it was true.
So I googled it and apparently it is true. This was good news to me, because I had an inheritance of sorts, which consisted of plastic containers and books packed with old stamps. I mean, I had no idea what to do with these things. I'm not a collector and have intention of becoming a stamp collector.
I thought about displaying them on a wall as art but it just didn't look good - more like a hodgepodge collection of art scraps. So here's the deal: Stamps are not legal tender.
You can ASK if the store will take them, but they're not legally required to take them. Sterling is the only legal tender in the US but even that has restrictions, as I understand.
