I may nitpicking a bit here, but here goes. I am organizing two old stamp collections I have inherited
and learning a lot along the way. So far, I am organizing them in glassine envelopes in boxes. My question is, is it harmful to store a stamp on its corner in an envelope vs. flat edge down (see pics?) I have noticed corner damage on some stamps, maybe bc they are picked up by the corners with tongs, and I don't want to contribute to that. Does it really matter?
