Something about it doesn't look right.
I'd say soft die fabrication.
May be wrong.
Will wait for the expert to chime in.

 to the CCF We need the weight and diameter to verify. It might just be me but something doesn't seem right.

The Singapore cent is 15.9mm diameter and the dime is 18.03mm. We discuss of about 2.13 mm difference which it is to much to have all dime design. The the weight: Singapore is 1.54gr cooper plated zinc and thick 1.1 mm. The dime press was put to strike for Nickel planchet at a thickness of 1.25 mm. .15 mm difference in strike will give a very weak strike. My opinion. Also an simple XRF will tell, zinc is zinc and nickel is nickel.

A Singapore cent would fit nicely into the collar of a 10-cent die Silviosi. In fact, without the collar die in contact with the entire planchet, and if a thicker host planchet, it would expand out nicely. Look at Canadian 25c struck on Cu-Ni 5-cent planchets, as examples. Zimmy has posted one example of a Canadian 1c struck over a foreign coin, on a copper-plated planchet: http://goccf.com/t/195006I believe Zonad has a nice 5c overstruck on a foreign copper-plated coin (Barbados?) as well. Sean Isaacs (Alliance Coin and Banknotes) has a 1992 loon dollar overstruck on a Bangladesh Taka. I have a Brazilian coin overstruck on a 1971 Canadian 1-cent. So while quite scarce, these errors do happen. A photo of the edge would be most helpful. Is it reeded all the way around? I noticed that you are in the US, so this definitely did not come in loose change. Did you acquire it from an error dealer?

SPP, Yes could happened, by the examples you give. If no mint employee it is involve, this kind of coins has .001% to be legitim. This coin in this topic is an overstruck. If no one from mint do not put a already struck coin back on the line then it is impossible to be an overstruck. Yes could happened to strike coins on foreign planchet but not overstrikes, and this happened. In 1995 if I am nor wrong was the German line S-Roll, now is B-roll. S come from single. So was three intervenient: one before the press to insure the correct flow of the planchets , the press operator and after the quality operator. So one of them put there an Singapore cent or maybe more. I see the tread you link, and I know very well the debate at TPG before to be certified. Pass because was not US coin, if was US coin was confiscated by the Agency. |

If the Singapore coin and Canadian coin where minted at the same mint, then you could believe the coin just got stuck in a hopper etc, but as they were not, I would be more leaning towards a mint employee messing with us.

A U.S. Mint press operator apparently intentionally overstruck the five coins from a 1982-S U.S. proof set with their equivalent Panama business strike dies. On a majority of the five coins, both the date and mintmark of the under type are perceptible. Undoubtedly a unique offering. LINK 2 Quote:
Few (if any) 1943 cents are known with "medallic" die alignment, and what are the odds of this occurring when the coin was being struck over a previously struck coin from another country? LINK 3 Quote:
This assumedly unique error combination was presumably a product of mint employee mischief, although a visitor at the mint or a supplier of planchets could also be the culprit.(#6733) (Registry values: P1, N2) LINK 1 All the coins in your Link are from a sale of the GEYER family's after him past, and was a Agency investigation and court debates. More, majority of the errors like this was from San Francisco Mint and dates of 1939 to 1944. The inside of the file I will not disclose. Conclusion is if with out an outside intervention, those error are almost impossible. Some could happened but not on this scale we see today after more then 50 years, and this because we are drive of a law prescription of 50 years. I have my opinion on and keep. In same time I could not say to any collector not to buy or sell. Personals choices. Like stamps. You are OTTAWA, correct? So maybe you know 50-60 years ago, me and my friends we take scrap papers from back of the printing and use to make fire to protect from mosquitos when we fish. Today those papers will be a fortune. All my best, Silvio

 This coin weighs 1.20 grams & matches the STD. for a 1 cent Singapore cent of 1.24 gm It belongs to a friend from work in Michigan who lives in Windsor Canada. I was evaluating his inherited coin collection for him when I came across this shiny penny, and at first glance I realized that it had a Canadian dime design. After further investigation, magnifying, photographing, weighing and researching. It appeared to me that it was indeed a 1 Cent Singapore coin based on the flattened design elements left over from when the Canadian dime was struck over top. They are both dated 1995 which you can clearly see on the coin. It has not been circulated because the coin is very clean and I believe the Singapore cent was uncirculated at the time of striking & the overstrike coin has not seen circulation either. Someone must have intentionally placed a brand new Singapore cent in the die chamber. In my opinion it's authentic. But, the question remains. Is this a valuable error coin regardless of how it came about. Is it worthy of having it authenticated & attributed by PCGS or other reputable outfit. I have yet to find any information on this variety of error.
