Stamping Tests
We've secured several blocks/heads (unsalvageable) of the 65-72 era for testing stamps/re-stamps using Thermal IR. We're tentatively scheduled to conduct the tests on the 22nd. I will post the results, what could / could not be determined, etc. Our scientist believes we will easily be able to detect those pads/stamps that have been altered, and possibly even be able to reveal the characters that were initially ground off.
