The first thing you should do is go to our section on " inherited
a collection", and read through it. http://goscf.com/f/57
This will give you some idea of what other people in your situation have asked, and how we have responded.
To continue with your situation, we will need some sort of description to work with.
Let's start with stamps, as this is a stamp collecting forum.
To start, we assume you knew the individual who owned the stamps. Were they are serious collector, who spent years collecting, or was he simply an accumulator? If you know, this can be helpful.
Are the stamps in a book (like a notebook or scrapbook), or album made for collectors? An album typically has pages with images of stamps on it.
If albums, is there 1 or 4 or 10 or more? Is there a name on the album?
Are the stamps simply loose in envelopes or shoe boxes?
Are they from the United States, or many other countrie?
The best way to start after answering the above is by taking some photographs so we know what you are talking about.
Set these items out on a clear table. Take a photograph of the group using your phone. Read the Forum instructions as to how to upload a photograph.
Take several photographs if there is a lot of material to deal with.
This will give us some idea on what to suggest next.
Once we see what you have, we can offer some suggestions.
