ABSTRACT:

Forgeries of coins can either be contemporary or modern. Already in the Middle Ages, it was well known that bracteates were considerably more difficult to counterfeit than two-faced coins. The main reason is that bracteates are struck with a more complicated technology originating from goldsmithing. Therefore, most bracteate forgeries have been produced since the eighteenth century. Compared to original bracteates, modern bracteate forgeries often have the following characteristics: 1) an incorrect weight; 2) a lower relief; 3) sharper contours on the reverse; 4) an artistically clumsy design; 5) evidence of being struck with the same die if there are several specimens; and/or 6) empty fields in the background.

The persons with intellectual disability have serious difficulties in language skills and consequently in the process of learning. The problems can be caused by Central Auditory Processing Disorders. In this paper we present research results on effectiveness of the Warnke method as a supporting tool in the development of language skills and in the process of education of children with such intellectual disabilities of mild degree.
