I found this strange quarter in my change today.
It doesn't stick to a magnet.
It only weighs 4.14g
It transfers marks to paper like lead would.
It's soft enough I can bend it.

That's odd - I would have thought a lead counterfeit would have weighed more than a genuine example.

My guess is a pot-metal counterfeit

Tin coins also bend and patinate in much the same way as the coin pictured.
Tin also has a very low melting point, so it is very easy easy to cast tin copies of coins in a 'shed job'. Tin has a density of 7.3 grams/cc, Lead 11.37 grams/cc.

Both tin and lead have been used in genuine World coins issued into circulation.

Contemporary counterfeit. I have seen and tested ones well into 1970s.

Mixture of tin, lead, copper and sometimes antimony.

I agree; to my way of thinking, that sort of alloy mixture seems most probable.
An alloy of this type is also suitable for striking and although it seems not to be the case here, is also good for plating with silver.
