That would be 1/41.6th of an inch. NYT has let us down. I just stacked 20 Roosies on top of each other. They came out to exactly an inch.  |

I just assumed the puzzle was referring to U.S. coins currently being minted.

I like your thin dime Hondo. Like Fred Astaire I prefer to call it a tired dime.
I will not accept paper play money unless it has the Small Seals in addition to the Great Seal.

Presumably most people haven't even heard of a trime.

There was a time when the NY Times crossword puzzle clues were carefully researched and vetted.
That ship has sailed like the Vasa.

US coins do not have legally defined thicknesses. Well, not directly. They do have legally defined compositions, weights and diameters, and the laws of mathematics state that if you know the mass, diameter and density of a cylinder, then the height (thickness) of that cylinder can be directly derived from that, mathematically. Doing the maths for a post-1853 trime, we get: Diameter: 14mm Composition: .900 fine silver (density 10.34 g/cm3) Weight: 0.75 grams This gives us: Volume: 0.07253 cm3 Radius in cm: 0.7 cm Volume = pi * radius^2 * height Height = Volume / (pi * radius^2) Height = 0.04711 cm So the theoretical thickness of a trime is just under 0.5 millimetres thick. That's an average; coins of course are not uniformly thick discs so an actual caliper measurement on an uncirculated well-struck trime is likely going to be higher as the coin will have a distinct edge rim and/or other high points which slightly increase the measured thickness.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

The NYT crossword clues are always consistent with tense and plurality. So since the clue was "Thinnest U.S. coins. . ." the answer had to be in plural form. So "dimes" works, but "trime" does not.

Yup, whoever came up with this clue should have researched the history of U. S. coins to make sure there were no other coins thinner than a dime. The NYT is known as a "newspaper of record." Alas, no more. |

If you're including more obscure US coins, I think California gold fractionals are even thinner.  |
