According to the Krause catalog this would be KM#40.2 with the erroneous LEY.925. It is made with copper-nickel clad copper and has a diameter of 38.8mm.
It has a mintage of 5,000 and a value of $20 in UNC condition.
It shows that none this year and version were made with silver. Others on here know how to use a specific gravity test to see if it is in fact made of silver. Unfortunately I am not one of them
