coins during that year, there are essentially just two types of 1967 Kennedy half dollars for collectors to acquire – the regular-strike 1967 Kennedy half dollar and the Special Mint Set (SMS) 1967 Kennedy half dollar. That didn’t deter coin collectors from acquiring the best examples of new coins from 1967, nor did it stop the hoarding of silver coins, which still circulated into the late 1960s, but at much smaller numbers than had been the case at the start of the decade. Mint continued the ban on mintmarks into 1967, creating a situation for coin collectors where there would be no distinct way to tell Philadelphia-mint coins apart from those made at Denver or San Francisco.
