I have no idea what year these were minted; probably sometime in the 20th century.
There are four numbers at the bottom of the obverse (the side with the two figures standing side by side), arranged kind of like how one would expect to find the numerals of a year-date. I don't know what the numbers mean, but it almost certainly has nothing to do with the actual year of issue of the coin.
I have noticed, looking at the several examples on this "coin" posted here on the forum, that there are two different "dates". The one in this thread, and the one in
this old thread, have the numbers "17" and "00". But on
this one and
this one the numbers are "51" and "40".
As for value, I have no idea. If they really are silver, then they're not "junk", but I'd only pay a couple of dollars for one. Augbauer sold his
right here in a forum auction for $1.
