Used photo-chemicals! They can help you turn “brass” coins into “silver” coins. Thus, 3 copecks (a glass of fruit soda) can be turned into 20 copecks look-alike (an ice-cream and a fruit soda!). Practical alchemy. Not sure if we dared to do the actual trick. Probably we did. At least we got some similarly processed coins back from an ice-cream sellers. That was so unfair!
