Cooper here! Today we’re talking about Roman numerals on US coins. <\/strong><\/p>\n Javier from near Madrid asked me a classic collector’s question: “Cooper, I’ve heard that all US coins<\/a> have Roman numerals on them. Is that true? And if not \u2013 where can I find them?” <\/p>\n Roman numerals are extremely rare on US coins<\/a> \u2013 appearing only on exactly 3 special gold coins since 1792.<\/p>\n The everyday coins you receive as change in the USA \u2013 cents (penny), nickels, dimes, quarters or half dollars \u2013 have borne exclusively Arabic numerals since the very first day of minting in 1792<\/strong> . Roman numerals are used exclusively<\/strong> on collector and investment coins: <\/p>\n Roman numerals look complicated at first glance. However, they follow only a few fixed rules. With these seven symbols, you can read any year on your gold coins yourself: <\/p>\n I<\/strong> = 1 \u00b7 V<\/strong> = 5 \u00b7 X<\/strong> = 10 \u00b7 L<\/strong> = 50 \u00b7 C<\/strong> = 100 \u00b7 D<\/strong> = 500 \u00b7 M<\/strong> = 1000<\/p>\n Rule 1 \u2013 Addition:<\/strong> If a smaller symbol is to the right of a larger one, it is added. Example: VI = 5 + 1 = 6. <\/p>\n Rule 2 \u2013 Subtraction:<\/strong> In certain combinations, a smaller symbol precedes a larger one and is then subtracted. Common combinations include IV (4), IX (9), XL (40), XC (90), CD (400), and CM (900). <\/p>\n Rule 3 \u2013 Read in blocks:<\/strong> Break the number down from left to right into thousands, hundreds, tens and ones, and add the blocks together.<\/p>\n Example: MCMLXXXVI<\/strong> = M (1000) + CM (900) + LXXX (80) + VI (6) = 1986<\/strong><\/p>\n In today’s standard notation, 4 and 9 are represented as IV and IX, not as IIII or VIIII. That’s why the 1989 Gold Eagle reads MCMLXXXIX<\/strong> . <\/p>\n Cooper’s tip:<\/strong> Compare your decoding with the label on the NGC or PCGS holder. Certified coins have the year of minting written there in Arabic numerals, so you can check your result immediately. \ud83d\udc3e<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n Europe does things differently in some respects \u2013 for example, Vatican coins display pontifical years in Roman numerals. The USA, as a young republic, said: “Practical first!” <\/p>\n Not on coins, but on the 1-dollar bill<\/strong> : At the base of the pyramid is MDCCLXXVI<\/strong> = Independence 1776.
