All the best.

I found this article....
Many people that have an interest in gold jewelry and coins often will claim that tarnished gold doesn't exist, however, that's the furthest thing from the truth. Pure gold will not tarnish, but it is rare to find jewelry that contains this pure element. When pure gold is added to alloyed gold, such as 18 carat or higher, this will also lessen the risk of tarnishing, with the exception of a few conditions. Tarnishing is generally only seen in smaller carats, depending on the base metals and the elements that each one is exposed to. For example, if a 10 carat gold piece has a decent amount of copper in it, it can oxidize, creating a red or black tarnish. Silver also exposed to the elements when combined with gold produces black tarnish.
Sometimes the way a piece of jewelry or something made of gold is manufactured can have an effect on its susceptibility to tarnishing. Items that are cast by lost wax casting and other methods that leave a micro-porous surface can actually cause the jewelry to trap various acids, compounds, and other elements which will cause a form of local tarnishing wherever the foreign impurities gets trapped.
When it comes to coin collecting, many consider a bit of tarnishing, or toning as it is called in collecting circles, to be highly desirable. Gold coins rarely tarnish because of their purity, but some exceptional toned coins exist and this toning makes them all the more valuable. You may want to clean your jewelry to have it restored to its original shine, but all coin collectors know to never, ever clean the tarnish off their coins. In fact it is a general rule to not clean your coins in any way. Collectors desire the antique look of an old coin and want that look preserved. Cleaning highly collectible gold coins can ruin their value.

First of all we are not looking at a coin but a medal shaped after a coin (size, missing back etc.) ...

As far as Gold coins are concerned there are only PURE gold coins and nothing like 14k etc.

I suggest you put it into lemon juice for a while and see what happens. I expect it to be either silverwashed coppr, silver or copper but not gold for sure. You can also easiyl if it is coing by comparing its weight to its size. Gold would be very heav.y How much doe sit weight.

However for sure NO gold. Sorry.

Regards,

Christian

Hello Andrew,

if it is brass or silver you can remove the tarnish with the lemon juice. However only leave it in there for a couple of minutes and then rub it with your fingers. If it is copper alloy you shouldn't use the lemon juice but leave it as is. With silver or brass use the lemon juice, then neutralize it using fluid soap etc. and put on same clear wax or oil afterwards.

regards,

Christian

Andrew, again I do not want to put you down but as everybody else has told you this is NOT gold. If you do not believe, just take it to any shop buying gold in Germany - there are plenty. They will not give you a dime for it as this is NOT gold. If it was just 14k Gold there would be NO tarnishing.

Also this is NOT a coin.

Of course you can dismis all of our oppinions but if you don't like them then you shouldn't ask. The guy by the name of Walker who told you about it on detektorforum.de is a foremost authority on European coins and you can take his word for granted.
