Is this a good proof like/deep mirror proof like test?

I'm trying to find an accurate test that I can use to tell whether a coin is PL or DPML (DPL). I came across this test when I searched the topic on the internet. I tried printing out the chart and put one each of my NGC-graded PL and DPL coins to the test, and both flunked: I can only clearly read the words 'SEMI-PL' in the fields of my supposedly PL coin, and I can only clearly read the words 'PROOF LIKE' for the the coin graded DPL. Do you think this is an accurate test? If not can someone suggest a better (and easy to apply) test for determining whether a coin is truly PL or DMPL (DPL)? Thanks.

The reflection test works better on a raw coin. When you try the test on a coin in a slab the light has to pass through the plastic twice and that reduces the distance you can read the letters.

 

Right on the money there.....

Oh, I didn't even think of that. That makes perfect sense. Thanks for the explanation, folks. Is there a better test you can recommend for slabbed coins? Or do you just have to learn to eyeball and recognize PL and DMPL (DPL) coins through experience (looking at a lot of them at shows, etc.) Thanks again.

 

Interesting site, thanks for sharing it, as I will find some new things to explore on the page~

 

Praise Jesus I don't have to worry about stuff like this.......
