High value tiles -[ HMM ]-

At one tile each, the five rarest letter tiles in a standard English-language Scrabble set. Other than the addition of two blank tiles (wild cards worth zero points) increasing the tile count to an even one hundred, the original game's letter frequency and point values have not changed at all since its 1948 introduction, not including 2004's Super Scrabble version boasting 200 tiles.

 

I originally shot the word Tile and its plural version, but I noticed others beat me to it.
