Question
QUESTION: Hi,
I recently acquired a 1877 Hamburg 5 mark gold coin that is in very beautiful condition. I've looked all over the net and all the examples I've seen have had a J as the mint mark. Mine has a W or maybe a crown, although it looks like a W to me. Have you any information about my coin? Thanks!

ANSWER: Hi Charles,
The W mint mark denotes you have a later copy, most of which are the same gold content as the real coin. I have seen a few of them, sometimes being sold as original 1877 coins, but they typically sell for gold bullion value and not the $500+ that an original coin brings in mint condition. I did see one that went for 115 euro, which is above gold bullion, but I believe the buyer was not aware.
Some coins with the W are also known in base metal with gold gilding, which are worth just a few dollars as a novelty item.
Thanks for the question! =)

QUESTION: Oh, thank you!
I'm very new to coin collecting. I bought the coin for $100, so I don't feel bad that it is a later copy. It weighs 2 grams. Sorry for the novice question, but what's the best was to tell if its plated or solid?
Thanks,
Charles

Answer
Hi again Charles,
When the coins start to be worn, the gilding comes off and shows the different colored metal beneath. The one in the picture I attached is such an example and you can see differences in coloration on the surface.
It's a bit more tricky with a mint condition coin. However, 2 grams is the correct weight. Assuming the diameter and thickness are also correct, it's a sure bet that it's solid gold. It would be virtually impossible to match the heavy density of gold with a mix of common metals.
At $100 you paid a fair price, but if gold continues to go up the way it's been lately it could prove a good investment.
Thanks again for the question! =)
