Internet auctions of ancient silver coins

Abstract

Internet auctions present a wide range of all types of jewelry, and despite the difficult conditions on the Ukrainian market, maintain a positive trend of development. The services of internet auctions of antiques are now used by numerous groups of the population. There is a need to further improve methods of data analysis on the operation of modern internet auctions, to define a list of necessary objective parameters for their evaluation for use by researchers and active bidders. The purpose of the article is to calculate the indicators for assessing the permanent state of the Internet auctions of antiques using the example of the sale of ancient silver coins.To achieve this goal, a working database of value indicators for silver coins presented for sale at the Violity auction, consisting of 203 samples, was created. After organizing the base of initial information, the analysis of the revealed regularities of the distribution of value indicators for silver coins was carried out and the indicators characte­rizing the feasibility of sale and the level of liquidity were calculated. Algorithms are thus described for calculating liquidity indices, the fall-rise of the market capitalization level, the expected multiplicity of the increase in the price of the product, as well as some others that are necessary for assessing the permanent state of operation of internet auctions of antiques. The calculation of indicators makes it possible to visualize existing market trends and have relevant objective data for verification of the results of expert works with cultural values.
