This is an antique, circa 1900, miniature sterling silver charm that could be used on a charm bracelet. It is stamped with the numbers 84, which are referred to a Kokoshnik mark and an indication of being Russian made. A better view of the stamped mark may yield more information on the miniature piece. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
