According to Krause, 27,600,000 10 ruble coins were struck in 1899. No mention of restrikes, as it does with some 20 francs (France, rooster / Swizerland, 1935D), Austrian ducats or 20 florint 1892 coins. Restrike or not, it's an astounding amount of coins produced that year, specially considering that for other dates only 125 units were coined.
