Etymology
古 combines 十 (ten) and 口 (mouth), traditionally explained as many mouths passing down stories from ten generations ago, symbolizing oldness.
Meaning mnemonic
Ten 十 mouths 口 telling the same old story over and over: that's how things become old.
Reading mnemonic
For コ, imagine an old, dusty coat hanging in a closet: coat -> コ, and the coat is so old it's falling apart.
