I'm not sure who is trying to get you to buy silver, but the current bid/ask spread gives bullion dealers a real incentive to push that metal.
He really should have something to balance out the scale...looks like you're a little gold heavy Not that there is anything wrong with that
By significant value I simply mean the price difference, I have a wall safe that I just got and there would be no way in hell I could get enough silver in there to amount to much of anything, I still like 10 oz boutique silver bars even though its been a year or two since I have bought any.
