| 正面描述 | At the centre of the obverse, within the aluminium bronze inner disc, appears the double-headed eagle emblem of the Bank of Russia as rendered by artist I. Bilibin, with wings displayed and a decorative heraldic style characteristic of the early post-Soviet coinage series. The Leningrad Mint privy mark (ЛМД) is positioned to the right beneath the eagle. A peripheral legend in Cyrillic reads «ПЯТЬДЕСЯТ РУБЛЕЙ 1993 г.» (FIFTY ROUBLES 1993) along the upper rim and «БАНК РОССИИ» (BANK OF RUSSIA) along the lower rim, both legends contained within the copper-nickel outer ring. |

Part of Russia's early post-Soviet wildlife series, this issue appeared during a period when the rouble was collapsing in real terms — a 50-rouble face value that had meaningful purchasing power at issue was essentially worthless within months as inflation ran into the hundreds of percent annually. The bimetallic format was itself a novelty for Russian coinage at the time, borrowed from technologies already deployed in Western European circulation issues.
The Black Sea bottlenose dolphin (*Tursiops truncatus ponticus*) subspecies depicted here was already under significant conservation pressure from Soviet-era fishing and naval activity in the enclosed basin.
