Pointless numerology
Getting ready for grocery trip, I was sorting the bills in my wallet so I could use up the smaller stuff first. Usually the wallet holds one or two 20s and a pile of 1s. This time it contained 20, 10, 5, and a pile of 1s.
10s and 5s aren't as common, so I noticed something that normally doesn't stand out. The green side of 20, 10 and 5 is all columnar. Each has a building in Greek temple style. The image of columns suggests countable digits like an abacus or a memory register.... BUT the columns are inversely correlated to the denomination. The 20 has 4 columns, the 10 has 8 columns, and the 5 has 12 columns.
The relationship isn't linear, so it can't be properly extended. Probably a good thing, since a linear relationship would require fractional (broken) or negative (upside-down) columns on larger bills.
Pennies and nickels also have columnar buildings on their back sides, and again the columns are inversely correlated to the value. But other coins have other stuff, so again there's no possibility of writing a formula.
