I was one of those people who used cash to avoid every aspect of my life being tracked electronically. That probably speaks to a guilty conscience, but the lazy way we’ve sacrificed privacy for convenience is something we may regret some day. Alas, Covid has crushed us cashless hold-outs. Aristocrats used to wash money and with good reason. It’s filthy. The result is that with food shopping one of the few legal reasons left to leave the house, I often find myself without a €2 coin to release a trolley. Ruminating on this regular nuisance, I spotted a lovely Twitter account @AnimalsonCoins run by enthusiast John Hyland, who wants to put animals back on our coinage.
