Identification with Problem Year - Prussia/Germany 10 Mark Gold 1887

Hi Numista Community,

Can you help me clarify the identity of this coin. It is a gold Wilhelm coin from Prussia/Germany 10 Mark. The issue is with the year. I am unable to find this year (1887) in any catalogs. Using a scale that measures to the first decimal place, the coin weights 4.0 grams. You can find the images below. What are your thoughts?

Thank you and Best Regards,
Jesse

Perhaps this older CoinTalk page is of some interest?

It is a fake.
The lettering looks too rough.
The obverse border has dots away from the edge;
whereas on the real coin (below) they are touching the edge, like teeth.
Similarly on the reverse - some are touching each other sideways,
and further round again some are away from the edge.
Depends on what other members think.
Apart from 1887 not existing.

Why make a fake/replica of a non-existent year (i.e. 1887)?

If it does not exist it is not punishable?

​no it is not, that is why the forger used a non existing date

​I think your coin may be a Schmidt-Haussmann imitation; they were made in the 1960s with designs of the Imperial gold coins from over half a century ago. See here: https://en.numista.com/forum/topic71343.html

Since imperial gold coins are a popular collection area, there are unfortunately many counterfeits here. This is most commonly found in the five-mark Reichs gold coins. Here, it is about 90% of all circulating pieces are counterfeits. The most famous counterfeiters of imperial gold coins were the German ophthalmologist dr. med. Karl-Heinz Schmidt and his sister Ilone Eva Hausmann. They coined in a big way hundreds of thousands of imperial gold coins very professionally and sold them as original Reichsgoldnachprägungen, which at that time (1959 to 1962) was still legal. Later, the reprinting of former German circulating gold coins without embossed marking was criminalized and the two were sentenced to prison in 1963 and fined. Until then, however, they had already brought so many Reichsgold falsifications into circulation that for many years even banks sold them as investment gold coins at the counter. Coin experts can spot the counterfeits today, so you should buy real gold coins only from trusted traders. Schmidt-Hausmann falsifications are very often offered especially in Internet auction platforms today.

Many of those imitations had impossible dates, much like yours; although I have seen mostly 20 Mark coins from them. They likely had some gold value, as they were sold and traded by jewellery counters, despite being modern imitations; so it might be worth seeing what metal your coin is made of.
