In 1932, $4.50 to $14, plus $2.50 for mounting. Inflation from 1932 to 1970 was 2.8 times. I also notice that they frequently don't mention the cut. IIRC, in 1970 or so, AT cut crystals in the single MHz fundamental range were about $1.25 single piece retail, and you could buy single pieces tuned to any custom frequency you wanted to order (not sure now if the price was higher than that for customizing). I can't recall how much TV makers were paying then for color crystals, but it had to be less.
