Hello Larry, you have great pieces!
Regarding age: I believe that the age of coins and cans can only be determined if they are almost unused. In everyday play, cans will also have been filled with foreign coins. Merchants, vendors and children also liked to mix the content so that it was easier to sell and play again.
Coins were sometimes found in my cans, especially with Lauer and Balmberger.
But be careful: the companies even helped out with deliveries! See catalog text at Lauer, Balmberge and Arld.
Have a beautiful Sunday,
Gunter.
here is his reply on box #41 in his catalogue ...the word box seems to always translate as "can "
