Maintain your wealth, I still can't wrap my mind around this.
Over the long run, precious metals hold value...not in terms of inflated dollars, but in terms of other commodities or products.
As the saying goes, 100 years ago you could buy a nice suit in New York City with an ounce of gold ($20), and today you can buy a nice suit in New York City with an ounce of gold ($1400). You could say gold went up in value ($20 to $1400), but really gold held its value, and the dollar lost its buying power. During that time, gold held its value and preserved your wealth (it preserved your ability to buy the same suit over time...regardless of what the dollar was doing). Money certainly did not hold its value during that same time. (I think gold is a better wealth preserver than silver, but we can see that an ounce of silver was about $1.40 100 years ago, and it is about $17.50 now, so similar principles apply.)
If you keep any amount of your wealth in US dollars, you might want to consider converting a small portion of that to PMs. If you don't keep any of your wealth in US dollars, then I can see why you might not care about PMs, because you are not interested in fungible mediums of exchange.
For the last hundred years (if my memory is correct) silver has averaged at $20 an ounce. For this discussion my great great bount an once of silver for $20. $20 back then was 20 days pay. Today the $20 could be 1 hours pay. Silver has not kept up with inflation. What I don't grasp is how that purchase by my great great maintained wealth?
100 years ago, a US dollar coin had 77.34% of an ounce of silver (and quarters and dimes slightly less). So, to have an ounce of silver in your pocket, you needed about $1.40 in your pocket. Now, it is $17.50. If you invested with the market, you can out perform silver. If you kept your money in cash, silver far out performed you. In times of crises, silver increased in value greatly, returning to lower values as the economy improved. Gold is climbing now, but I'm not using it yet. I'm holding it until a time of true crisis, when the dollar becomes greatly inflated.
I personally have a very small portion of my wealth in silver or gold, as a hedge. If the dollar crashes, I will lose most of my savings, except for that savings kept in the form of PMs and other commodities of value (grain, etc.).
