Sir Kaiser, this still seems to be the coin topic du jour, and the Mint web site is also highlighting it in a featured topic on “Explore how quarters enter circulation to reach your hands.” Here are some finer points: Coins circulate between banks, businesses, and people. When people keep coins to drop in change jars, piggy banks, or collections, they take the coins out of circulation. The U.S. Mint produces more than 10 billion circulating coins a year. New coins account for less than 20 percent of the total coins in circulation. The average lifespan of a coin is about 30 years.

Major D, maybe the conundrum is solved, as Chris T alluded to: the change (coins) is being stored in “coin jars” by the public. As illustrated in this infographic by the U.S. Mint titled “How Coins Circulate” circulating coins are initially produced at the U.S. Mints and ultimately end up in coin jars.

It has a high relative humidity and we call it a woodie.
