Commodity estimation of antique small and miniature plastics from bone and wood

Purpose. Investigation of the main principles for commodity evaluation of antique small and miniature plastics from bone and wood, as well as forecasting of their liquidation value. Methodology. Standard methods of regression analysis were used for the commodity evaluation of antique small and miniature bone and wood plastics. Results. A complete list of procedures and calculations necessary for carrying out commodity evaluation of antique ivory products and valuable wood articles, as well as for forecasting of their liquidation value, is described. It is demonstrated the significance of the analysis results of the market related items current state for the creation of a collection of standard models and its further use for performing of comparative operations. An example of calculations of the forecast value is presented using the mathematical model proposed by the authors, which is quite suitable for practical use for the cost forecasting of high-art ivory and valuable wood products on the international market. Scientific novelty. It is proposed the division of cost indicators of small and miniature bone and wood plastics into commodity groups and the introduction of specific values of value, determined as the ratio of the value of the object to its diagonal gross size. Practical value. The procedure for the specific indicator of the current cost of small and miniature bone and wood plastics calculation: the ratio of the declared value to the diagonal gross-size of the object, which allows to take into account the products size in the evaluation procedures, as they are indicative of the overall assessment of the technical complexity of the work on the creation of the subject
