Venezuela has an interesting numismatic.

You wrote: "1 oz of silver can buy you now few months of food in Venezuela". This was true in some extend a couple of years ago. But it is no longer true. The basic food basket, is more than 100USD, per month. The prices of food are in international levels, but in many cases, you do not find the goods, so you have to paid higher prices. The wages are very low. A monthly salary of 50USD, is considered good for the current standards. But it does not cover even the food. This is one aspect of the tragedy that Venezuelans are facing.
