When did this Happen - Snakeskin Proofs??
I just received my Territorial Quarters Proof Set and could not help but notice:

When did the US Mint change from "Frosted Proofs" to "Snakeskin Proofs™"??

I decided to change calling the bathroom the John and renamed it the Jim. I feel so much better saying I went to the Jim this morning.

I do think they have a vacine for coins also..
As a side note, the coins are the best I've received from the mint in many years but that finish..................Yuckola!

.............so lee, you "coined" the expression.
Weird finish for sure. Bet it looks nice in the sunlight without magnification.
I had a friend who was a radio DJ called Freddy Snakeskin.

Interesting, and GREAT pictures, Lee.
One thing for sure.... seems to be way different from the older traditional frost on the coins....
I don't remember the exact science behind it all but after that "experiment", all subsequent proofs seemed to have a much more pronounced frosted effect to them. My guess is that this is what you are seeing with 19Lyds excellent photography.
Does this seem reasonable? I'm totally guessing here.

I bet if you were to rub them, it would not feel like cloth, even though it looks like it. Funny thing is, we will never know, cause even I could not bring myself to rub a proof...
<< <i>Perhaps they are using lasers to impart the frost to the devices (on the dies). After all, they do appear to be many very tiny 'micro pits'. Rapid, high energy burst impacts by laser? Might be a faster cheaper way to get the frosted finish.

Impossible. Everyone knows that the metal of the die conducts heat instantly, therefore the die would be a puddle of metal before such an effect could occur
Thanks, Frank.

What? 'Snakeskin Proof' or the word 'Yuckola'?

I have to agree in part with messydesk, it may be a technological advancement in coinage, but IMO it takes away from the artistry somewhat. Old world craftsmanship replaced by modern processes. I guess I'm surprised how long it lasted to begin with. Hey we keep buying, right?

It's kinda like "shinola."

Sorry. But the original sounds even better than the paraphrase:
"It's a myth. Metals conduct heat instantly. The entire coin would be at the melting point before a laser had any effect"

Huh???? Ever weld steel? Cast metal? Solder wouldn't work, spacecraft could not enter the atmosphere, a lead bullet would melt and run out the gun barrel, on and on....
Lasers are used all over the place to cut, etch and “engrave” metal. The mint’s system offers better control than masking and the product is approximately the same as sandblasting. (Well – not to sharp-eyed collectors.) Laser frosting also offers the possibility of many sorts of textures and detail enhancement not previously possible.

The subject was whether hairlines can be melted away with a laser to blend in with a proof surface.
Don't suppose they are using EDM to impart the devices in the dies? I wouldn't be suprised that this move has been made with the advances in die making technology. This would allow then to totally avoid traditional squeezing of hubs and dies and the risks associated.
EDM: Electronic Discharge Machining (for those wondering). Basically a the form is cut on a copper block (called an electrode in this case) and it is plunged into the steel at a very slow rate. Electric then arcs across and "burns" the form perfectly into the work piece.
It is typical to see such surface patterns under magnification.

Still, very good eye to pick up on that.
