по фото предмет видится старым. но я лично в невежестве своём не слышал о такой игрушке ни разу
думаю что Саша Басок что то может рассказать на тему.
Вот нашел приличное описание, но на их вопросы оно не дает ответа.
Да, проходы этой вещи 13.000 и 15.000 долларов.
Alexander II, 1855-1881
Trial Striking using the die of 20 Kopecks 1863. Struck at the St. Petersburg Mint in 1876 using the method of the American engineer George Champney. 21.4 mm, 0.09 mm thick. 4.13 gm. Silver. Reeded edge. Cf.Bit 597 (Bitkin lists only a plain edge); cf.Uzd p.655, fig.36; Cf.Pagani (Prove) 105; Cf. Mont. 6; cf.CNI 467, 32. Obverse of an Italian Gold 20 Lire of Vittorio Emanuele II, 1863 (Torino). Imperial eagle obverse of a Russian 20 Kopecks. Only the second known example with a reeded edge (the other example was featured in the Русский Нумизматический Дом sale, November 7, 2009, lot 253). Toned Choice extremely fine
In April 1876, the American engineer George Champney of Boston petitioned the Russian Minister of Finance to present his new technique of die preparation, which included the ability of copying directly from the coin (Champney patented his method in the U.S. in 1872 and in Great Britain in 1875). By ministerial decree, Champney was allowed to make his presentation at the St. Petersburg mint. There his technique showed good “promise.” According to the Chief of the St. Petersburg mint (see: Вел. Кн. Георгiй Михаиловичъ «Описаниiе и Изображенiе Нъкоторыхъ Ръдкихъ Монетъ Моего Собранiя», pp. 32-34), Champney conducted his experiment by using the die of the 72 Fineness standard 20 Kopecks. He deliberately selected an unapproved die which featured a high relief Imperial eagle to show that his new technique could be used with high-relief coinage. He married this to the obverse of an Italian 1863 20 Lire.
Previous study of this fascinating type was apparently limited to one variety and in some cases based on earlier writing without necessarily an actual example to study. Hence earlier scholarship may not present a clear picture. In researching these pieces we were presented with the unique opportunity of comparing two flan varieties of the issue. The two examples presented here were clearly struck on different flans. The smooth edge type is much thicker and slightly smaller than its reeded edge companion. Bitkin calls this experimental piece a “Trial striking on a flan of 20 Kopecks.” Comparison shows this to be incorrect as the 20 Kopeck flan of this period was larger than both these mules and featured distinctly different edging. So it is not a trial striking on a 20 Kopeck flan, but rather a trial striking employing 20 Kopeck dies. It is quite likely that Champney making an important presentation to high-ranking officials at the St. Petersburg mint used coin blanks that he had brought with him. Clearly after four years of promoting his technique, Champney would have his presentations down to a science and would have all the “presentation tools” at hand.
