Good afternoon all. I was wondering if maybe there may be a thread or link already around for what are the best methods of finding out the watermark on mint/gummed stamps. Or feel free to start a discussion here as I would love to know more on the subject. I do ok with the used stamps but have no clue on the mint ones. Any help or direction would be appreciated.
Or if you don't feel like spending $20 on 2 ounces of WM fluid, Lighter Fluid (Ronsonol) works just as well and is used by almost all of the leading experts.
An additional word of caution on lighter fluid - some permanently leave the stamp smelling like lighter fluid. Always test it out on a garbage stamp or two first.
