For those most common of stamps that literally turn up by the hundreds, I've taken to throwing them in a donation bin to donate to the Holocaust Stamp Project
http://www.foxboroughrcs.org/studen...amp-project/The funny part is that once in awhile I'll be looking through my collection, and I'll (embarrasingly) notice that some of the stamps that are going into the donation bin are better than ones in my own album. Those common-as-dirt letter-rate definitives were some of the very first stamps I mounted when I was first starting back collecting, and I just mounted the first copy I had, which often wasn't a great example. Being among the most common stamps, I'd rarely go back to look at them or see if they needed upgrading, so I'll still notice some real dogs once in awhile in my collection amongst those most common and worthless stamps.
