1940 D LWC DDR (1-DR-001)

Well that is a nice find.. even the 'dot' and EPU is doubled

Excellent!

Brand,

Great question. When consulting any of the reference sites/sources, always, always, always read the description first. This tells you exactly where to look for evidence of hub doubling.

VV does a great job of loading lots of pictures, but often they are intended to show die markers or die states rather than just the doubling, so if you start by looking at their photos you'll spend time looking at aspects not directly related to the doubling.

The attribution provided (1940D-1DR-001) tells you that the OP consulted Copper Coins website as this is the format they use and their description reads:

"Light extra thickness is seen on the lettering and dots in E.PLURIBUS.UNUM, the top of the O in ONE, the right and left wheat ears and the horizontal bars of the E in AMERICA."

Some of the reference sites will provide cross references for other sites and some don't, so it helps to learn the various formats so you can compare the coin directly to the reference source.

On this DDR, the dots are elongated and the bottoms of some of the letters in EPU are wider than normal (E, L, & U are the easiest to spot). Not all Wheat cent DDR's involve EPU, but it's one of the more common areas (and easiest) to find them.

On a Wheat cent reverse the elongated dots are one of the best signs as they rarely develop due to circulation wear, and the direction of the elongation, towards the center of the coin, should also be present on the EPU, but most visible on letters with bottom bars.

When you see the elongated dots AND see the fatter letter bottoms that's a sign of hub doubling because it indicates the hub or die moved or was misaligned between the first and second hubbing and indicates the specific direction of the movement.

If you saw fat letter bottoms AND sides AND tops you would more likely be looking at circulation flattening because, rather than all over, doubling occurs in a specific direction (the direction of the movement/misalignment).

Looking at circulated coins makes the identification of doubling difficult sometimes, so here's another example of a DDR where the dots in EPU are in a particularly pronounced "egg" shape. Notice the bottom of the E, L & U are fatter on this coin than on the normal, non doubled variety.

Hey Brandmeister, check out doubleddie.com for detailed info on the various classes of doubled dies.

here is the class VI info http://doubleddie.com/203948.html

As HGK3 stated, it's the dots, always the dots on a wheat DDR. That's the easiest way that I've found to identify them. Circulation might flatten the letters, but the dots will not elongate with circulation.
