Go look at a long term gold chart - wild swings from high to low.
Gold was $1100 in 2011 and 10 years later was 2000. And that is common. So the ruble peg to gold be disastrous the next time gold goes down in price in dollars. Yuan are pegged to dollars. Russians will be getting slaughtered on their China buys.

Yes, please look at a long term gold chart. The price of gold was about $40.00 when we were taken off the gold standard in 1971. It has remained very stable compared to inflation, unlike the dollar.
I saw a sign posted at a gas station for .25 gallon gas. However, you had to pay in a pre 1965 silver quarters, which I think is worth about 4.50 today.
I thought that was the a great teaching example of inflation and the stability of real money (silver and gold) all rolled in to one funny sign.
Post your definition of "very stable"
