I volunteer at a charity shop, and we were recently donated a big bag of old stamps.

There are literally thousands of them. Being no philatelist, I'm not sure what to do with them.

I'm spending my day sorting through them. Most are British, some recent, but a lot from the '50s and '60s which may be worth something. Googling one at random gave a £4 price.

I have neither the time nor inclination to try and sell them individually in the shop or on eBay. Any suggestions?

Also, some of them are just bog standard, fairly recent ones. I recall certain charities used to want those. Is that still the case?

Thanks,

Ed
