Please don't do it in titles or posts. * found this 1909 vdb coin in a box of jewelry I purchased. it had a loop to wear as a pendant. I tested for 10k gold and was good but someone told me that it was common for people to plate them. I scratch a little deeper and sure enough copper, so I decided to take the loop off so that it could be a coin again. after carefully using the grinder the loop came off but now I'm more confused, I can see the gold then the copper but now there is silver under the copper . I again tested 10k gold and it holds some but I thought the coin was suppose to be all copper. did the mint make 1909 penny of other alloys? Report this Post to the Staff

ikeyPikey Rest in Peace United States 233 Posts	Posted 01/12/2017 10:22 am If you plate gold directly onto many metals - and copper is one of them - over time, the gold 'disappears' down into the copper. If memory serves (don't count on it): "amalgamation". You need a barrier layer; ~~electroless nickel~~ rhodium (the memory is serving!) is a common modern choice.
