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™"?? image
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.

    great close-up pics. That's quite the odd finish.
  • Huh good term "Snakeskin Proof" you should put a TM after that one...

    It clearly has Leprosy. Burn it!!!!
  • thats the same finish that they did on the 2008 proof buffalo.

    Too much silica sand used during washing of the plancet.


    I do think they have a vacine for coins also..image

    Since the first pezy PROOF I have thought the mint was using some sort of digital process to generate the frosted appearance, your pics really put a great closeup on what I was seeing.

    While the coins look nice in hand, under the loupe that finish is simply terrible!

    As a side note, the coins are the best I've received from the mint in many years but that finish..................Yuckola!

  • Those are some excellent photos Lee. Nicely done.

    Weird finish for sure. Bet it looks nice in the sunlight without magnification.

    I'm seeing something like that on the edges of the BU Wm. Henry Harrison dollars - sorta fabric like texture.

    I had a friend who was a radio DJ called Freddy Snakeskin.

    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.

    One thing for sure.... seems to be way different from the older traditional frost on the coins....

    The “frosted” surface is generated by laser, not by sandblasting the relief. The laser offers more precise control and w/o magnification the difference cannot be easily noticed. Under magnification, it resembles snake skin or mechanical engraving.


  • FullStrikeFullStrike Posts: 3,797 ✭✭✭
    Remember those Silver Wildlife Medals a couple years back? Well those were supposed to have used some new experimental laser-etching process to achieve the frosted devices.

    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.

  • Isn't this the same process they used on the presidential proof sets? I seem to recall some talk about it then. Of course I haven't looked at one as magnified as 19Lyds photos.

  • I think it's kind of cool looking, myself!

    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...

    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 image

    What? 'Snakeskin Proof' or the word 'Yuckola'? image
  • messydeskmessydesk Posts: 13,951 ✭✭✭✭
    The 2006 Reverse Proof ASEs were the first coins to have this finish. Then in 2007 the presidollars had it as well. It only stood to reason that eventually the Mint would put it on all their proofs. After all, it has effect of hiding the inferior artwork with a noise pattern while being aesthetically inferior to the traditional frosting. How were they supposed to pass that opportunity up?

  • 19Lyds Thanks for the additional pic's.

    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?

    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.

    Hey machining guys:

    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.

    This type of finish has been seen in firearms and knives for many years, and likely is done mechanically.

  • GREAT THREAD! Ive never seen this before on a coin, but it looks like Frank said, machining.

    Still, very good eye to pick up on that.

  • Just a guess, but it's possible the Mint is now using laser technology to etch this new "snakeskin" surface as opposed to the old, traditional method of sandblasting. I have read articles that attest to the fact that the Mint is incorporating all kinds of computer technology that speeds up the process of proof coin production. If a computer program is guiding the laser, that might explain its mechanical, uniform appearance.
