Hi,
it's a russian kopeck similar to mine's (https://en.numista.com/catalogue/pieces113598.html), minted during the rule of tsar Alexei I in the mid-1600's. There are a few more varieties of it, yours is impossible to determine because the mintmark is located below the horse's feets (which are cut on your coin).
Your coin is mostly preserved, nice find!
Personally I don't like both side. Strange damage with some part of the letter on it and strange space around the spear might be normal, but the letter Ч which is upturned set me thinking that it is fake.

It is not upturned "Ч", this is "Ь" - the last letter in word "Мiхяiловчь", and this coin should be identified as catalog number KG#961 or KG#963 according to the catalog of Russian coin by Kleschinov and Grishin.
It is from the initial period of rule of Alexey Michailovich (1645-1650) and it is genuine.

If you know how these are made, and how much they cost, it is not worth to make forgeries....
But fakes exist....
Since I didn't have this coin in my hands, I should have said "highly probably genuine" - but I don't see any tell-tale signs of the forgery... Yes, fakes do exist but what I see are mainly the fakes of rather rare (and expensive) varieties, not something as common as a kopek of Alexey Michailovich. Though, with the constantly growing prices of this type of coins on the market we should expect to see the attempts to fake more common varieties - and our colleague from Bulgaria has already sent us a warning signal...
