1968 S LMC Doubled Die?

Well you are getting the hang of it....but...again the MD bug bit ya. This is called "high bounce MD". I explain it like this. When you hammer a nail into wood, the hammer will bounce a number of times per hit. This is physics, the release of energy. The hammer doesn't land exactly in the same place each time(no matter how hard you try). Your coin received one of those numerous hits. A good carpenter uses this to his advantage through muscle training to use minimum whacks per nail. Same physics principle in machine presses, release of energy, plus a myriad of machining factor, adjustments, wear, maintenance.

Now, two other things here on the 66-68 cents. The master hubs were older, worn out, making the details larger and has metal movement/die deterioration on the hubs. Hence, I call them balloon letters are common. On your coin, those are normal size letters for a 68, not an increased size. Remember, hub doubling ALWAYS INCREASES size, slightly to readily evident, and not always with a distinct division line either. Hope this helps!

Personally, I think the Class 6 Rotated Hubs are the toughest to learn to spot, I'm still working on those. The slightest rotation, particularly of same sized hubs, is extremely difficult to see. On those, I take KNOWN date/MM cioins and scope each. To randomly check each coin becomes a fools errand really quick!

Sorry Crazyb0, but again, it's not Machine Doubling. This is actually a genuine Doubled Die Obverse. There's absolutely no reduction of the devices, so it's not Machine Doubling.

Mr. Coop, I guess I've become so gun shy of posting DDO's that I don't make a typed comparison. But, it looks and awful lot like a DDO-007. Especially with coin in hand. But then again I absolutely understand what Crazyb0 is telling me as well and both would make sense. I'm almost as confused now as I was when I first looked at this coin!

Well I always thought it was a master die because they were so easy to find. In searching BU rolls you would find several. I asked Bob that question and he assured me it was a DDO. But always had my doubts until I read John Wexler's thread. Then it made total sense. It was a working hub issue. With that being an issue, you would have several working dies with different mint mark locations. So I'm not confused anymore. It is a Working hub issue that passed the same doubling down on every die it was used on. It makes sense now to me.

Some experts are calling the doubled dies, others not as they are from a working hub. I feel John has it correct. In time all with realize who is right and wrong. But it just takes time. On site will call a 1956-D/S on two different dies, the other denies both. So it is still up in the air. So don't sweat the differences. Keep them marked as what source they are using, you may want to put what all three call it on the 2X2. Eventually it will be sorted out.

Thanks everyone! At least my mindset is on the right track while looking at and for Doubled Die cents. And, it will definitely be put into a 2x2. I'm glad to have it.

I hope you do too Mr. Coop.
