I am hoping someone can offer advice on this 1974, clearly all copper, quarter. Is this an error? Any info? Thanks so much.   |

@therese, for sure it is copper colored, but if it is struck with a missing clad layer then it will be significantly underweight. Otherwise, it is either surface staining or someone has copper plated this quarter at some point.

An outdoor metal detector find. The color would be a lot darker if it were a missing cladding coin. Also the devices would be weaker:  |

Copper Nickel develops this sort of color, if t has been buried for some time.
I suspect that the nickel has been leached out of the surface layer. That layer may be no more than up to 100 microns in thickness.

Okay so the weight is 5.5 and here are the pics of the rim. I see some silver in the ridges. So IG this means that the coin had it's sliver clad and wore off? Thanks for your help.   |

The clad is still there, it's just discolored and looks like copper. The weight is under spec, but I would expect this on 46 year old coin with this much wear.

It does look like it's missing the clad layer, but the devices are really strong for that. I agree about maybe the copper has leached through, but I really have no idea.

I've sometimes tried to clean dug-up British 10p, 20p and 50p coins, found with my metal detector, with metal polish just so they will be accepted in shops. I've known them turn this kind of color when cleaning them. I reckon this could be a coin that's been buried for a while and someone's tried to clean it with metal polish. The wadding type of polish (sold in the UK as 'Brasso') tends to give this effect. I normally use something more abrasive now if I want to clean current coins that I've dug up, after a bit of an argument with a bus driver over a rather pink 50p a few years ago!

Here are some perfect images for this thread. I dug these 6 quarters 2 days ago. Posting to show the difference that can occur to the same metal in similar soil within about 20' of each other. Organic sandy soil with weeds, grass, and two were found among the roots of a tree.   Words of encouragement are one of the major food groups.
