I don’t consider investing in gold a prep because it is so expensive and will have very little influence on whether or not you survive a disaster.
Silver on the other hand I consider a secondary prep. Silver may benefit us in a long term situation, but the prepping basics are more important than having silver coins. What do you think?
I've looked into silver but have yet to find a need to buy over food, water, Solar, Off Grid Living preps. It's hard to say really if it will have any real value.
I believe both would be a great bartering item but they are quite expensive to aquire. Maybe get a little at a time or so trades for some now before shtf. On the other hand maybe getting more self-sufficient where you will not have to barter much would be a better option.
