Alexei Romanovich!
Looking up your cross and his description, he decided to check the lists of those executed in Butovo Polygon, the date specified in your /8 /September 21, 1937 /, there is no priesthood, given the priest Antoni Polanski - these lists are complete and published on the Internet. Specifies the address:
http://www.st-nikolas.orthodoxy.ru/n...list_date.html. similarly numbered 223
http://ricolor.org/history/rsv/kgb/butovo/1/. Priest Anthony (Anton V. Polyansky, 1875 - 9/21/1937), of Moscow., p Resurrection., pp. Ostashevo. I should say that there is a clergyman containing clear, who is white, ie just married priest and monk who, ie, Monk, having ordained a priest.
On this basis, identification, likely with the specified Martyrs wrong, it most likely the other person and may be also a martyr. Indirectly, this is indicated by the fact that the inscription on the case was written with the new spelling and it is likely to fail - increase the photo - is written - "iromonah", and in Slavic inscription should be written monk - as written in all official documents and now. Also, in a word Anthony in your case there is no letter i, ie you have not quite true /'Fr Antoniiy Polansky ".
For many people this information is important and it should give very careful.
As for the price, it is very high in terms of jewelry this cross is not a masterpiece, I agree with Toinen.
