Truepenny

A truepenny is an old English word for an honest person, and before that, for a coin of genuine metal. Merchants tested coins by dropping them on the counter: base metal lands dull; the real thing rings true.

Shakespeare knew the word. When the ghost calls out from under the stage, Hamlet answers: "Ah ha, boy, say'st thou so? Art thou there, truepenny?" Old truepenny: the one you can rely on.

That's the standard this product is held to. Not clever; sound. Everything on the record, everything checked, and the rules that matter built to hold. An old word, given a modern cut.

Drop it, and it rings true.
