VERY GOOD ILLUSTRATIONS!!!!! WILL CERTAINLY USE THIS INFORMATION AS TO DIFFERNIATE ALL MY 1988 and 1989 Lincoln cents!!!!! I have a "POORS MAN" 1955 Lincoln cent that needs this information!!!!

1989P 1DO-005 with class VI extra thickness in the date.

Great explanation. My question would be on that 1989 that seems to have much thicker numbers for the date and this classification you give it. Are they rare and if so worth more? I seem to have a great deal of these laying around and not just that year. 1964, 1982 and several others. Thanks.

Below are several 1943 Lincoln cents.

A: shows a coin with faint offset Die Deterioration Doubling (DDD) indicated by strong flow lines SE and present on the 4 and the mintmark (S). Being that the doubling is on the mintmark, in the same place and offset in the same direction is indicative of this type of non-collectible doubling.

B & C: show a coin with plating that has enhanced or somehow caused severe doubling. Whether it is from a corrosive introduced to the coin's surface to remove some of the old plating, or the electroplating that followed, something has caused the coin to have strong doubling on the date. Plating can be glossy, slick and thick, or thin and matte with even streaks throughout the surface. The doubling tends to have an orange peel look to it as opposed to strong flow lines. The plating can be thin enough to retain almost all characteristics of the coin's design as well as die scratches. Doubling involving plating is rampant on eBay- and is often sold as doubled dies or RPMs. Be very cautious when acquiring 1943 doubled dies or RPMs.

D: shows details of 1943-S DDO-001 for contrast between hub doubling and the previous mentioned forms of doubling.

Below are closeup shots of typical die wear on nickel or clad coinage. The example used is a Jefferson nickel. The DDD can be present on either side of the device. It can appear mushy, distorted, somewhat like MD. It is often uneven and present with strong flow lines.

I've got an article on DDD coming out in next week's Coin World. Nothing particularly original in it, but it's a useful refresher for folks who don't visit LCR.
