Token of Appreciation.

Found in a pile of old coins that was given to Yahel by grandpa Eli:

The asimon (Hebrew for "token") was the only means of payment in Israeli public phones until the end of the 80s, when it was replaced by the telecart. I remember one year, when the price of phone calls went up so steeply that analysts concluded that the investment in asimonim was better than the dollar, or the stock market. The only problem was, how to buy them in large quantities. In any case, the asimon was a common cultural token of those days. A mythical pick-up strategy for young people was to approach the subject with one of these tokens, and tell them "call me up some time".
