Hello, I have many stamp from France and one of them could or could not be valuable. Am new at this with the stamps and would greatly appreciate any of your feed back.
P.S I know the gum is not so good in the back.
All of the stamps you are showing have significant damage. This will greatly reduce any value they may have. Go to your local library and see if the reference section has a recent copy of the Scott Stamp Catalog that covers France. If any of the stamps have a high value you may still be able to get something for them.
I have order the electronic Scott catalogue 2021 volume 2. Thanks for the advise. appreciate.
