Basically small custom computers in the early days
Internal computer modems are less than a dollar.
External computer modems (pre-broadband) will run$2-$10 depending on board and ics, some have gold cap Motorola and zilog chips etc. some of the earliest ones that list as baud not bps or Kbps have netted more than $10 each from 8086 class gold caps, heavy gold sandwich boards, and the like, commodore, Atari, Apple, and Ricoh come to mind.
Broadband shelf modems (cable modems) are about $1-$2 depending on brand and revision
Rack modems and commercial/business cable modems run $5+ (they weigh at least 5 lbs and look like late 90s dell and ibm cash register computers. To help you know.
