A common Deitsch tradition tonight is to put a coin (or coins) outside on your windowsill overnight tonight.
Some variations specify that the coin/s should be silver. Others specify three denominations (nickel, dime, quarter, etc.) of coin. Some Christian interpretations are that these are for the Magi on their way to Bethlehem (PA? lol), while other interpretations definitely have this related to magic that easily fits in with Berchta making the rounds as a beggar.
If the coin/s are still there in the morning, bring them back in and "Was hawwich yetz wa ich ganzes Yaahr haawe." ("What I have now I will have all year.")
If the coins are gone, then the need was greater elsewhere, and you will receive good luck for aiding another.
