Exploring a tin of Brooklax

I went scratching in some old boxes and found a tin labelled Brooklax. Now for those of you who do not know, Brooklax was or possibly still is a laxative.
The tin rattled when I shook it. So I opened it and found an amazing treasure trove.
Hint: Note the dates on the coins and yes, I know it is illegal to damage coins, but somehow I don’t think anyone is gonna pursue me for damaging these coins.
So join me in an exploration of a tin of Brooklax.

The oldest of the lot.
This is a really historic coin. The Renten Mark of which this coin is fraction was issued to try to halt Inflation in 1923. The attempt failed utterly.
