What is a cameo finish?
Of course, the finish on that silver dollar was no different than any other modern commemorative silver dollar. Phil is right, the finish on modern commems has been "matte' since 1994. There have also been some regular issue mattes, notably the 5c coins in the 1994 and 1997 Coinage and Currency sets and the $1 coin in the 2001 C&C. The "satin" finish on 2005 Mint Sets are also indistinguishable from some of the matte coins. The grading services react in different ways to this dilemma. ICG notes the difference in $1 sacajaweas on the slab. PCGS calls the 2005 coins "satin finish" and identifies the '94,'97 nickels and '98 Kennedy 50c as "special mint set." NGC routinely identifies the satin coins and the special coins as "SMS." NGC also gives cameo designations based on appearance, not proof/non-proof status, to any coin. There are "cameo" business strikes in almost all the series so designated by NGC based on their cameo contrast, independent of the method of manufacture. Regards, Tom |

What is a cameo finish?
Well all commems are at least double-struck ... often several times.
Any collector style coin is at least double struck. I was at the Franklin Mint in 1999 and they were striking some Life of Christ silver medals. They were striking them 4 times each....which is a feature that was not advertised. Its probably easier for the US Mint to just use proof dies then blast them for the matte UNC finish. These modern commems definitly DO NOT have the same finish as the UNC coins in the annual coin sets. NO DOUBTS in my mind. Visual inspections shows that the UNC commems are minted with much more care than standard UNC sets. The surfaces are nice a frosty whereas the usual UNC coins sets have a shiney surface. Phil DeMayo wrote: Michael wrote: The three requirments below would apply to the unc versions of modern commems. Would they? Do they receive multiple strikes? Are they struck from specially prepared polished planchets like proofs? I am under the impression that they prepare the dies the same then sand blast them with fine granuals to give them the matte finish. So technically it costs more to make the UNC versions that the proofs. How so? Proof dies are also sandblasted to achieve the cameo finish. The fields are highly polished, the dies chromium plated to extend die life and each die is used to strike a limited number of coins before being retired or refinished. Do you have any proof that all of the above (and more) is done with the unc dies. If not, how can they "technically" cost more than proof dies? The UNC Marines dollars is no doubt a matte proof. Well, that 's up for debate. The argument started in 1998 when the Mint came out with the Kennedy Collectors Set which contained an unc RFK commemorative dollar and a Matte Silver Kennedy Half Dollar. Packaged side by side it was obvious to most that both coins had the same finish and some dealers began hyping the unc RFK commem as being a matte proof. Of course, the finish on that silver dollar was no different than any other modern commemorative silver dollar. You can call it anything you want (and possibly be wrong)....but the Mint simply refers to them as "uncirculated".....not matte proof. Now another possibility would be for the dies not to be prepared as well but say 90% as good then the flaws are covered by the sandblasting. Mike Marotta wrote: Michael wrote: Aren't Matte Proofs used all the time here? The UNC versions of all Commems are essentially Matte Proofs. No. By definition, a proof coin must be (MUST be) 1. struck multiple times. 2. from specially prepared dies 3. on specially prepared planchets. |

I stand corrected on the cost. While I firmly believe modern UNC
commes are matte proofs...it probably does cost more for the diemakers to mask out the mirror surface with masking tape to allow for sandblasting of the frosted areas. This I have seen in person.

What is a cameo finish?
I have a website with some coins with a gold plated cameo on each piece
in the collection. see http://www.proud-collector.com/8/3/collection.aspx for examples. -------------------------------- http://www.proud-collector.com/ Michael wrote: Having never really collected certified coins, I would like to know what is meant by the term cameo when used in the grading of both proof and mint state coins? |
