Hi Pensfan,
Welcome to the group.
There are articles out there about what to do if you
inherit a stamp collection. Easy to find if you google a little. And browse around in this group.
How you go about it really depends on you and what you want to do with all that material - and how much time you want to spend.
If there is a stamp club in your area, that would be a good place to start too.
Glad to have another person in Mississippi in the group. I'm in a small town between Jackson and Meridian!
Good Luck!
Dave N.
