PS.
I have a five Mark coin that dates from 1937 with the Nazi swastka and eagle, but I didn't want to attract the wrong crowd at bars

My gremlin bell was being tugged on so hard by the gremlins that the attachment ring was nearly worn thru.  As soon as I can get a round 2it, I'll reattach it.

I have a small silver cross on a very tiny bead chain that I put around the base of my left side rear mirror.

I keep my good luck charm on my keychain.  It's called a house key and so far it has kept me from being locked out of my house!

From the time you could use one to "call someone who cares" I carried a dime in my wallet. Unfortunately a few years ago I switched wallets and forgot to switch the dime. Never felt the need to find one to replace it. One thing that hasn't changed since I was a kid is carrying a folding knife. I've needed it a few times to get either me or someone else out of harms way over the years.

When I was looking for my bell, I found a few different "reasons" for carrying a bell on your bike.  Google it.  I choose to use the interpretation that the ringing of the bell keeps the evil road spirits from attaching to your bike, thus keeping you safer while riding.  
Other reasons include having one as a remembrance for fallen riders... when you clean your bike and your bell, it reminds you of the fallen ones.  Receiving one as a gift, some believe, doubles your luck!

Justin_o_guy2,  
Here is the coin you ask about.
If I remember my history correctly, (and that is a big “if”), the German public forced General Paul Von Hindenburg out of retirement to run against Hitler. This was in an attempt to slow down the National Socialist Party's power grab. Hitler was elected Chancellor and Hindenburg was elected President. Shortly after Hindenburg was elected he “died”, and Hitler abolished the position of President. He created the office of Fuhrer, which combined the duties of the President and the Chancellor. And the rest is History!
