1968-S variety?

[jon]

I couldn't find a listing for this in here or CONECa. Anyone know if this is a known variety?

It is machine doubling. Notice that both the mint mark and the date are affected by this form of common doubling, which is a sure sign that it is neither a doubled die or a RPM.

I wondered if that was the case since it really didn't fit in either catagory. If there are enough machine doubled coins discovered, do they become a variety? I'm just wondering because I see quite a few of these for sale on oBey.

Machine doubling is on the bottom of the totem pole as far as errors are concerned. The reason why is fairly simple; the doubling is not consistent and can vary from strike to strike. Since machine doubling occurs during the strike and not from a hubbing fault, it is considered an error and not a variety.

Why so many do sell on Ebay is mainly because people who are not educated concerning this anomaly type think that they are getting something great. NOT!

I have one in my watchlist and wanted to check on it before bidding. I guess I still have a lot to learn. I don't quite understand why machine doubling is on the bottom of the totem pole. Maybe it just hasn't found a following yet? It may be the next Traildies or Madclashes? I think they're pretty unique myself but I may just be way out in left field.

I'm actually a fan of massive machine doubling, where large areas of the design are affected by significant lateral shifts of the die. Like this specimen:

In some cases you get wholesale duplication of raised design elements.

Your cent would be an example of minor machine doubling, which is quite common.

I think it would nice to have a website devoted to extreme examples of machine doubling, both the push-doubling subtype and the slide doubling subtype.

Thanks Mike. I feel better knowing that I'm not the only one who appreciates them. I REALLY like the nickle you linked to. I would Love to own that one.

I arranged to purchase the nickel from its owner.

I've viewed (in hand) 3 of the five (5) known Mint State examples of the well known 1916/1916 DDO 5c Buffalo Nickel. Once at a Longbeach Show I view a PCGS-64 example (No MS-65's exist to-date) that had in addition to the Die-Doubling a good amount of Machine Doubling - it was wild visual vibration to look at. A good one to image on a web site dedicated to Machine Doubling.

My exprience with machine doubling (mechanical vibration) is that many times it takes place at the beginning of a die run before the coining press is "tighten-down". I noted this because the lack of die deterioration in any way (cracks, chips, cuds, etc.) on most of the coins I have examined. Something you might want to check further.

Mike, very Sweet aquisition. Really unique.
Danester, That sounds very intriguing with DDO AND Machine Doubling.

I've seen plenty of middle and late die state coins with heavy machine doubling. But I haven't made any detailed study of relative abundance across the different die states.

Here's a couple of foreign coins with machine doubling. The top one has most the lettering except for Juan Carlos, the bottom is mainly on Juan Carlos's lettering.
