1. The coins used in monetary exchanges in a particular country. Drachmas are no longer the coin of the realm in Greece. You'll need euros if you want to buy anything here.
2. By extension, something that is especially valuable in a particular field or area. You better get this unique idea of yours patented—intellectual property is the coin of the realm for inventors.
