This is one of the Czech coins, the 50 Kč (50 Koruna) coin. I believe it was minted in 1993, as thats what it shows under the lion, but the year 1993 is also when these types of coins were first minted (got that from wikipedia). 1993 is the only date on the coin, so I am probably correct. The 50 Kč coin is the highest value of coin used in the Czech Republic/Czechia.
If you look closely, notice parts of the lion in the outer section. I don't know why that is like that, but it's not an error they are all like that.
The Czechs have an agreement to change to the euro, but they haven't changed yet, so Czech coins might be something to collect in the near future.
*Edit* Whilst being a modern coin, it's got some sort of beauty that most modern coins lack. I like that
