The coin doesn't read "50 koiieek", but rather "50 КОПЕЕК" (pronounced "kopek" in English) - the coin is from Russia (or its predecessor, the Soviet Union) and it is written in the cyrillic alphabet. (Pre-Soviet Russia also had coins denominated in kopeks, but the spelling in Russian was different.)
The coin's numismatic value depends - the 50 kopek coins issued by the Soviet Union between 1924 and 1991 could be worth between about 10 US cents and 70 US dollars, depending on year and condition, and a few of the proofs from the 1920's are valued at US$400-US$500; the more modern ones issued by Russia since 1997 are worth little more than a US dollar in Uncirculated condition, and face value in circulated condition.
From a foreign exchange standpoint, only the Russian coins issued in or after 1997 have any value - as of February 9, 2011, there were about 29.4 roubles to the US dollar, so 50 kopeks is equal to a bit under 2 US cents.
Note, finally, that the early Soviet 50 kopek coins (1924-1927) were 90% silver and contained 0.2893 troy ounces of the metal (worth, with silver at US$30.30 per troy ounce as of February 9, 2011, about US$8.76), but their numismatic value is almost certainly higher.
