Hi to all one stamp I have shown before, the one on the bottom I have shown previously, but the one on the top is another version that I have found.

Both have been examined with a 10X eye loupe, a stereo microscope and examined by UV and show no indications of having come into contact with any chemical or chemical tampering.

These are from a collection that I purchased a few years ago, and which I am slowing going through, who knows what else may be in there.

Regards
