Saw a site that had a printout to measure reflectivity of a coin. Can't remember where. If you could read certain parts of the printout from the reflection on the coin, this was its measure of reflectivity. Wondering if anyone had a link to it. Thanks
Hard to say what site you saw, but it depends on what scale you want to use. NGC says that for a coin to rate DMPL you have to be able to read a newspaper in the coin from 6" to 8" away. PCGS says 4" to 6" for DMPL. For PL NGC says 4" to 6" - PCGS 2" to 4".
