2000 Belize 1$ - Doubling

1970 S LMC - Possible RPMM?

1990 D RD - Post-Strike Plier Dmg [U]

UPDATE: After some back and forth on the coincommunity.com forums and closer investigation of the edge showed a slight bulge, I'm 99.9% convinced this was post-strike damage using some sort of plier device.

The idented areas are on this nearly line up back to front, but do not exactly. The cut looks similar to what I've seen on struck-through rim-burrs, but I never seen one that occured on both sides like this. Here are what I see as options:

1. Defective Blank - the blank had a wedge of metal missing from it for some reason and the metal flow during the strike was not able to fully close it and fill it in.

2. Some type of strike-through, though I'm not sure what would cause a slightly mis-aligned similar gouge on both sides of the coins.

3. Post-strike damage. I'm least confident in this because the features of the gouge indicate this defect occur pre-strike or during the strike instead of after.

1963 D BHD - Suspect Doubling [U]

UPDATE: Machine / Strike doubling.

Probably machine doubling, possibly RPM?


Most likely Machine Doubling (no doubling visible on the inside of the D).

Nickels with Doubling [U]

UPDATE: Both of these were caused by die wear / die deterioration.

1973D KHD - DDO (RePhotographed)

Still not sure on this coin so I rephotographed it. Ring lit with half the ring's light blocked and the other half diffused. Still not liking the outcome but it continues to show notching on the I, N, and G of 'IN GOD' which is indicative of doubled dies.

Foiled by Light! [U]

UPDATE: Well not necessarily 'foiled' by light, more like a 'lesson learned' that how you light a coin can determine how well a coin's variety can be seen and sometimes may give an impression of doubling that may not necessarily be there or is so minor it's not worth getting excited about. I tried a few other lighting techniques after these photos were taken and I've come to the concensus that the 1971D and 1973P's are not DDOs, but that the 1973D 99% likely is.

1971 D KHD


1973 P KHD


1973 P KHD (#2)


1973 D KHD

Am I seeing things? [U]

UPDATE: It's not unanimous whether these coins are DDO or not, but regardless if it is a DDO and that is notching we see, it's so minor that it's not worth getting excited about.

Ok this is getting a bit ridiculous, two more Kennedy halves showing notching on "IN GOD" - these shots are of two 1973 P halves from the SAME ROLL. Perhaps there's some master doubling on this year?

1973 P KHD - #1


1973 P KHD - #2

1998D KHD - Struck Through Rim Burr [U]

UPDATE: Confirmed. Struck through Rim Burr.

I think I found another Struck Through Rim Burr, this time on a Kennedy half-dollar. This one clearly shows where the metal was removed from.

1971D KHD - DDO [U]

UPDATE: It's not unanimous whether this coin is a DDO or not, but regardless if it is a DDO and that is notching we see, it's so minor that it's not worth getting excited about.

I think i just found a second KHD doubled die in the same day after never finding one before and searching through around $40,000 in halves. Doubling looks most evident in the 7 of the date.

1973D KHD - DDO [U]

UPDATE: The lighting may have played a part in the notching we see here so I relit it a couple of different ways and tooks some additional photographs. See later posts for an update.

Pretty positive on this one since the notching is extremely evident on the "IN GOD". Only reason I doubt myself is because the doubling on "WE TRUST" is not as strong as on the example in my cherrypicker's guide - but this could possibly be a late die state.

2000D KHD - Struck Through Grease [U]

UPDATE: Per the folks at Coin Community Forum, this is an extreme case of Struck Through Grease, though I still don't know what caused the wear lines off the 'TR' in 'TRUST'.

1971D KHD - DDD [U]

UPDATE: Confirmed - Die Deterioration Doubling

I'm pretty confident it's either strike doubling or die deterioration / die polishing doubling since the strike is so weak, but just in case ...
