The U.S. 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. 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.
With an absence of mintmarks on U.S. 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. Neither coin is particularly scarce, as 295,046,978 regular-issue Kennedy half dollars were made in 1967 and 1,863,344 SMS Kennedy half dollars produced that same year.
1967 Kennedy half dollars are extremely difficult to find in circulation today, as their 40 percent silver composition prompted hoarding early on, and they are therefore quite difficult to find in pocket change or even in bank coin rolls. When silver values are at around $20 per ounce, 1967 uncirculated and SMS Kennedy half dollars are worth about $5 each.
