Uncirculated coins are minted on special presses and struck with greater force than circulating coins. This was a quote that I pulled and added to my comment earlier. And it says "Uncirculated coins are minted on special presses and struck with greater force than circulating coins".........I believe I dug that from a U.S. Mint article or somewhere......so then I guess the question should be ....."Is this really a LIE ? Or is it true that they are struck on "special presses" with "greater force than circulating coins".....I don't know....but that quote, as I said, was NOT mine, I pulled it for reference to add to the comment I was making with Metalman. If that quote is false, I'd like to know ! Can someone just call the Mint and ask them ? If this IS false.....then I change my opinion COMPLETELY and agree with Metalman and Jbuck, however, if this "qoute" is TRUE, then this should be talked about and understood by more people. Disinformation EITHER WAY is not a good thing. I wanna know dang it ! Edited by eaglefoot 01/05/2009 11:02 am Report this Post to the Staff
eaglefoot Pillar of the Community United States 6326 Posts	Posted 01/04/2009 12:39 pm It's Sunday morning......just here at the office to work out on the treadmill......and I just real quick looked through the Mint glossary and such.....this is all I could find so far and now I gotta go. Quote: At the United States Mint, we use the term uncirculated when referring to the special coining process used to make the coin, which gives it a satin finish. Uncirculated coins are manufactured using the same process as circulating coins, but with quality enhancements such as slightly higher coining force, early strikes from dies, special cleaning after stamping, and special packaging. Uncirculated coins may vary to some degree because of blemishes, toning, or slight imperfections. Higher coining force....that would be the "struck with greater force" thing. Early strikes.....better quality "Special cleaning".....better quality You see, to me, it should not be a "matter of opinion"......it either is different in substantial ways.....or it isn't. I don't have the time to research this or find any good references, but if someone else could.......it'd be nice that's for sure. Because if I'm buying basically the same dang coin just for the packaging to say "Uncirculated Set", then I'll be just slightly annoyed and upset !... So.........IS "SATIN FINISH" A BOGUS TERM OR NOT ?......(and I don't mean just barely enough noticable difference to be able to make the "claim",...it should be substantial enough to be different and seperate) Maybe a new topic should be started for this "Satin Finish"......

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 01/04/2009 9:41 pm Business strike coins are struck on Schuler horizontal presses containing 4 dies with a capacity of 750 coins/minute. I believe the older presses had a capacity of 200 or so coins/minute. Making an educated guess, I would say that they might strike the satin Mint Set coins on these older, slower presses with the striking pressure turned up a notch or two. I would bet the handling is different as well- business strikes ride around in ballistic pallets with a few hundred thousand coins but I doubt the Mint Set coins get this bulk treatment.

You can see this all for yourself when you tour the Denver Mint! All of the Uncirculated coinage is made in its own smaller area of the Mint (north of the huge main area with the high-speed 'business' strike presses, that dump into Kevlar-bagged pallets), on smaller low-speed Schulers. Right with all of the small Schulers, on the north side of that room, is the packaging area where they are packaged into Mint Sets. Quote: jbuck: "I would love to see a picture of it if you decided to build it." I still need a loose Satin Finish Colorado P, and I do also have a loose Silver Proof Colorado-S that I could use in the center. The difference between the Satin Finish coins and the BU business strikes wouldn't be as obvious in photos as it is in person. The cartwheel effect on this Satin Finish D is just outstanding! It looks like a 24mm version of a burnished "W" A.S.E. This Set would be an eyecatcher in person.... Edited by DNA 01/04/2009 10:15 pm Report this Post to the Staff

Don't remind me I have been to Denver once, in 2005 on my honeymoon. We had plans for touring the Mint but everything conspired against me. Post 9/11, you had to make Mint tour reservations through your Congressional Representative or Senator and undergo a mini-background check. In February of 2005, I sent an application to my Senator's office and waited. In mid April, I finally got a reply that they were no longer scheduling Mint tours and the only way I could make a reservation for a tour was at the Mint itself(no phone or interent reservations). Ok, I thought, just a minor set back. Our honeymoon was in early May and we spent the first part of it in Colorado Springs, arriving in Denver on a Tuesday. We went down to Colfax St to make reservations and the tours for the entire week were filled with school groups I wanted to schedule it for that Friday(which was going to be my 30th birthday) but instead all I got to do was see the inside of the giftshop which was basically a construction trailer sitting next to the Mint On the bright side, it sounds like my educated guess was correct Edited by biokemist6 01/04/2009 10:30 pm Report this Post to the Staff

Odd, I would not expect a satin finish coin to have a pronounced cartwheel. The light scattering effect of the satin finish should mute or blur out much of the cartwheel. I would only expect cartwheel on a piece whose satin finish is close to being worn out. Report this Post to the Staff
