Please feel free to contact me at firstname.lastname@example.org. I would also be willing to help with valuing a Callcard collection.
N.B: If you are looking for a collection valuation please include as much information about your collection as you can. A picture can speak 1, 000 words so taking and attaching some photos of your collection would be a great help.
