This is outside my collection area, but since no one else has replied, I might as well share what info I can dig out and hope someone with more information chimes in.
These emergency coins from 1715-19 are popular to collect among Swedish collectors (although not by me) and are not hard to find in good condition. There are ten different types in the series and each type shows some variation in design elements. Your tin copy, for instance, looks more like this example of the same coin: https://www.ma-shops.com/wallinmynt....php?id=8561
There is not much information about copies, but I can find some brief notes (in Swedish) about the existence of copies of other coins in the series made of lead and bronzed copies made of unspecified material. So, yes there are copies, but they don't seem to be very common. According to the Swedish Royal Coin Cabinet, there are no known contemporary copies of these coins, so most probably your tin copy is modern.
