Stamp Albums, collections, Postage

I have been a stamp and cover collector for 50 years and love old collections (envelopes are known as Covers). I am looking to buy large and very large collections. (I Pay Cash!) for postally used envelopes with the stamps still attached, stamp albums, stock books, and almost all postal related items including unused stocks of mint stamps. Send me a message and lets discuss what you have.

I am looking for pre-1940 items, US and Foreign. I am very interested in old foreign, China, and Hong Kong envelopes are a plus. I also buy unused postage but it has to be a lot of postage to make it worth the effort. Modern first day covers and the covers with gold stamps have no value and sorry but I am not interested in that.
