Pretty neat find! I found this additional info for you:
"These 1 agora coins were minted by Israel between 1960 and 1980. All but the last year (1980) were minted in aluminum, with the 1980 coin in nickel. Modern coins like this which are made of non-precious metal are worth face value, and collectors might pay more than face value if you have a coin that is absolutely, fully uncirculated. " This info was from CoinQuest.com
