Proofs have been minted since the since the 1830s in various denominations with a few gaps, mainly around WWI and WWII. Proofs have not always been sold in sets like they are currently, you could purchase them individually or in small sets such as minor coinage(cent, 2 cent, Three Cent, and nickel five cent) or a gold set. The high end collector of the day would purchase all of the denominations available.
In regard to the date on proofs, it is accurate for the year minted. The one exception would be the 1804 dollars which were actually minted 1834 and later.
