Technically, Proof coins were made for collectors. Most Bust Type proof coins are not real proofs, but specimen strikes. I had this conversation with Walter Breen many years ago. The TPG services are now realizing this, and refusing to slab previously called proof coins as proofs. My 1828 Dime is a perfect example (was PR-64 PCGS, now in a NGC holder as MS-64). The pedigree lists it as proof as early as 1890. Now to answer the topic; Actual proof coins were first struck in the 1840's to satisfy collectors. In theory, the new coinage machinery of 1836-38 could have been in use to strike proof coins, however there may not have been a demand for proof coinage then.
