Hello, I came across the website and am hoping that this community could be of assistance to me. I
inherited a stamp collection several years ago and am now considering selling the collection. I had a dealer look at it and offer me $200, but my uncle sold an identical collection for around $1500. I am just a bit confused and don't want to be taken advantage of. I have included a link bellow to a flickr account that has images of the pieces in the collection from the 1880s to the 1970s. The collection also includes a very large number of stamps from the 80s, 90s, and 00s. Any guidance that you could provide would be greatly appreciated.
