Question

1. The main disadvantage of using shells as money, instead of coins, would be a lack of:
a. durability
b. portability
c. uniformity
d. divisibility
I think its B. portability?

Answer 1

I would say a. Shells are portable, but break easily. You could have special exotic shells for high value money. I would see the main problem to be the ease of counterfeiting.

Answer 2
