1791 Galle (Ceylon/Sri Lanka) VOC 2 stuiver dump

 

India. Just taking a look at this photo and was thinking it was overstruck on another coin. The more I looked at it made me wonder if it is a die clash. I've been collecting for years but never learned much about errors until I joined this forum. Still don't know much but it does look like the coat of arms from the reverse under the denomination. You can also clearly see the frill above the date on the reverse on the obverse.

 

I think there is a name for that, where the devices on the other side of the coin can be seen as if pressed right through. I am not very knowledgeable about such errors and terms, someone on here will probably enlighten us directly. Good looking EIC coin, and definitely has something going on there. I might as well post an Afghan coin, 1934 25 pul. I think those are die cracks on the obverse, plus a cat hair and some dirt and grease.

Thanks. I have a few struck through grease. This looks like the obverse die was damaged by contact with the reverse die leaving an impression. I highlighted what I am seeing on the obverse.

@coin_nut and @Muzyck - "internal metal displacement phenomenon"

First caveat - I'm not expert but constantly learning. Second caveat - I'm taking the ANA's correspondence course - from whence my information derives. Third caveat - I'm not the sharpest knife in the drawer . . .

Applicable to US coins, the ANA teaches that the "technical term" (or phrase) is "internal metal displacement phenomenon" (hereinafter IMDP). Apparently, this occurred often with US wheat cents; i.e., "ghost of Lincoln" occurring on the reverse. The error or variety community places this issues under "die errors" on the PDS (planchet, die, striking) timeline of the existence of a coin. I'll quote: "Heavy design transfer: When a die nears the end of its usefulness, it often exhibits the major central design of its opposing mate. This design is transferred from one die to the other through the striking of the coin metal." My lesson booklet refers the reader to Alan Herbert's Minting Varieties and Errors, fifth edition, New York: House of Collectibles, 1991, page 158.

That seems enough to me but I will quote more from the giants if asked to do so. I do believe this issue was raised in an earlier post in this thread of another - and I think it involved both coin_nut and Muzyck!!. It took the issue coming up twice for me to get off my lazy buttocks and put two and two together. So, caveat four, I'm not only not the the sharpest knife in the drawer, I'm awfully lazy.

 

Thanks. I think that was what I was looking for in this post...

Couldn't find that description but giving me the description of IMDP confirmed it!

That being said, I still wonder if what I see on the India coin is a die clash, the transfer being where I highlighted the image in yellow.

 

OK, I am ignorant. What is a "die clash"?

 

Using Ethiopia as the last post, here is a 1912 H East Africa & Uganda Protectorates 1 cent

Using Kenya, here is Somalia:
