That's what makes it so frustrating.

Very rare! It would be quite a find! $30000 in VF according to Coinsandcanada.

Looks like some one tried to clean it at one time...Maybe why it looks so light coloured..just my opinion.

Would a grading service be able to determine it (via XRF if nothing else)?
If so, and if you think you have one, mightn't it be worth the grading fee for a 30K coin?

I can test it on the XRF in my lab at work - if you want...

The easiest way is to take a piece of glass and make a tiny scrape on the edge..Look at the underlying metal...Brass will be yellow the others orange.... You must use glass because it will not react with the brass... If you scrape it with other metal it will have a reaction....

FYI - the Krause catalog and Numista lists bronze for those years

SPP, that would be great. It more than likely isn't but what the heck! Can you PM me your address?
Thank you!

And the results are....  Bronze! At least it starts with "BR".  Thank you to SPP for testing and thanks to Fuzzy because I would have wondered why it was bronze and not copper. |

XRF testing is quite cheap and non destructive.
An X - ray is bounced off the surface of the metal and a fluorescence pattern is analyzed to give a quite accurate analysis of the proportion of the various metals in the surface of the alloy. Trace elements are easily identified.
I have seen such equipment in use at a coin show to identify fake coins.
Nevertheless I would think this is a bronze coin despite the yellow color, and is maybe the result of the environment in which it has been for quite some time, probably years.
Some Chinese struck 10 cash coins of the early 20th century were nominally bronze, but were often struck in brass copper or bronze. In this case the variation in alloy is of little importance.

I've been looking at my cent duplicates and have noticed that some are yellower and some are more chocolate-y. I think heat and sunrays might play into the colour changes. That and cleaning with acids, growlie :(

I'm not sure but I think some are mostly copper and the bronze ones are copper and tin. I think the 1859's are a lifetime study group in themselves...  ... I like them for that reason. I never get bored trying to figure them out! I enjoy the vickycents.com]site. More fun to be with them. |

Hello! New, here. I have an 1859 large cent that I bought about 30 years ago, advertised as a brass strike curio. Don't worry, I didn't pay much--at the time, the brass strikes were mentioned, but not listed, in Charlton's. A few years ago, a dealer said he didn't think it was brass, though he hesitated when he saw the yellow highlights on the reverse. (See the uploaded photo.) He suggested checking the color of the fresh metal by making a small scratch on the edge with something non-metallic. I'm still searching the house for a diamond big enough! Cheers -- John  |

Why would you need a diamond to scratch a soft metal? Find yourself a bobby pin or a staple.
