Rahrah, your coin is, sadly, not made of gold, but from an alloy of aluminum and bronze. You have a 50 kopiyok piece from Ukraine, only worth face value, which is around 6 US cent at the time of writing. A collector may pay a few dollars for a fully uncirculated coin with amazing eye appeal.
1 KOPIYOK: stainless steel
2 KOPIYOK: aluminum or stainless steel
5 KOPIYOK: stainless steel
10 KOPIYOK: brass or aluminum-bronze
25 KOPIYOK: brass or aluminum-bronze
50 KOPIYOK: brass or aluminum-bronze
All the denominations, dates and mint marks are of low value, as described above. But there are a few coins tht stand out in value. Hope you have one of these.

For 50 kopiyok coins, to the right of the final 'к' of 'копійок' there must be five dots and the reeding on the edge of the coin must be segmented. Otherwise the coin is not *special*.
It quite unusual for such modern coins minted in non-precious metal to reach these values.
Any coin that is not *special* like described above is mostly worthless to a collector.
