Canadian quarters in washers and dryers at the laundromat in the US and in Canada, old 20 French frank coins, if I remember correctly, for the parking meters, which probably works in the US as well: every country has their slugs (see definition No. 3).

Since the introduction of the euro, it has been easy to pass off certain lesser coins for euro, at the least the one and two euro coins. Pictured here is a 1 bolívar fuerte from Venezuela that was passed off to me as a 1 euro coin.

According to Amsterdam newspaper Het Parool, people who have been to Thailand are freely using Thai 10 bath coins, which are worth about 24 euro cents. Although there’s a king and a temple on the 10 bath, the similar colour scheme confuse folks who don’t check these things, especially in a bar or taxi. Well, that’s how I landed the fuerte.

“We estimate that lately at least 10,000 of these coins are circulating in the Netherlands, says Sander van Golberdinge, Deputy Director for Detailhandel Nederland — the umbrella organisation for all retail trade in the Netherlands.”
