It's time to keep the change around. I always pull out older change even if it's beat up since there's more valuable metal content. You can expect to see more older coins during hard times. I saw an elderly lady spending a $5 gold receipt bill at a Kroger in Texas about 1986-87.
Planning ahead already saved me $100K in my IRA by bailing from the market before it tanked.
