During the three year period of absent mint marks during the 1960s, is business strike coin production quantity known for each mint? If not, do we at least know which mints produced which denominations? I've assumed both Philly and Denver churned out all denominations, but perhaps that's incorrect. As for San Francisco, maybe just cents and nickels, as they did later that decade?

Only one Mint was used for these 3 years. The San Francisco mint. But no mint mark was used to indicate this. Philly and denver mints did not mint any coin at this time frame. The following is a statement from the PCGS web site: https://www.PCGS.com/news/collectin...of-1965-1967Quote:The mid-1960s was a colorful time in American numismatics, with the United States Mint making a series of changes to accommodate a terrible coin shortage brought on by widespread hoarding of 90% silver circulating dimes, quarters, and half dollars as the price of silver rose. To lessen the cost of producing circulating coinage, the United States Mint switched the composition of the dime and quarter to copper-nickel clad, reduced the amount of silver in the half dollar to 40%. And to help dissuade the removal of coins from circulation, the mint temporarily removed mintmarks from all coins beginning in 1965. During that same year, mint officials stopped making annual proof sets and uncirculated sets, and instead focused on the production of circulating coinage. But all was not lost for collectors, who were offered a new type of annual coin product called a Special Mint Set (typically abbreviated SMS). These Special Mint Sets consist of a single Lincoln Cent, Jefferson nickel, Roosevelt dime, Washington quarter, and Kennedy half dollar and represent a numismatic marriage of the uncirculated sets and proof sets. The coins in the Special Mint Set were struck at the San Francisco Mint with polished dies and blanks and boast higher-quality finishes than seen on typical uncirculated coins. However, SMS coins were generally not struck multiple times (as with most proof coins) and in many cases were not polished at the mint to the same degree as proof coins. Thus, coins in the Special Mint Sets generally do not match the quality of typical proof coinage |

If I'm reading that correctly, it only refers to SMS coins. I was always under the impression that coins were struck at all three mints during those years.
It also doesn't quite make sense that they'd stop production at the two biggest mints while trying to solve a major coin shortage.

1965-1967 was not just SMS strikes These were also business strikes as with 1968 & 1969 .  Proud Member of The Black Sheep Squadron !

Thanks for the explanation. It's also odd that 1964 had SP coins, too. Not sure why minting those was done when the use of silver was stopping? Is there any relationship in the minting process between those 1964 SPs and SMS coins? Were SMS dies common ones that were just utilized differently?

Looks like there is no data on this topic. Until we know better, I suppose we can guess that the coinage pattern of 1968 might have been copied from 1967, specifically that in 1967 Denver minted all denominations, Philadelphis minted no halves, and San Francisco made only cents and nickels.

In my post up above I was referring to the SMS sets because I misread the topic title. any time someone talks of these years I usually think of the SMS sets not the circulated coins of these same years However, here is what I found on this subject so far: My reference is: https://coins.thefuntimesguide.com/1965_coins/Quote:
1965 Coin Shortage
The United States was facing a coin-shortage crisis in the early- to mid-1960s.
Silver prices had risen significantly above the $1-per-ounce mark.
The U.S. government had to take action against the fact that the silver in its coins was becoming worth more than the denomination stamped on the coins.
In 1965, the U.S. began striking copper-nickel clad dimes and nickels and reduced the amount of silver in half dollars from 90% to 40%.
No Mintmarks On Coins From 1965-1968
But that was not the only move that changed the face of U.S. coins. To discourage the hoarding and collecting of U.S. coins based on mint marks, the Coinage Act of 1965 banned the use of mint marks on coins.
Though the Act required the absence of mint marks for 5 years, in 1968 Congress approved the return of mint marks.
Since 1968, all mint marks have been located on the obverse (front) of coins, instead of the reverse (back), as was the general case until 1965.
Special Mint Sets From 1965-1967
The changes of 1965 did not stop there.
Proof sets and mint sets (sets of coins packaged for collectors containing uncirculated and pristine examples of each year's coinage) were also halted for 3 years.
In their place came the "special mint set," which contains uncirculated examples of coins. Many of these special mint sets contain coins with "proof-like" finishes.
These represent a better-quality, more reflective surface than the coins typically housed in mint sets.
The special mint set was produced from 1965 through 1967, until production of regular mint sets and proof sets resumed in 1968. |

Fascinating info nonetheless. I have a number of these sets, especially in the long, narrow boxes. I agree that is was odd that they kept production of coins low in this period. Did they need the materials for Vietnam War? Not unusual for war time to alter coin production, as you know.

Wow, so the mintage data does exist for that period, thanks Conder.
Just 284 thousand 1966 San Francisco halves. That would have made them the key date of the Kennedy series. Combine the more recent study of die markers with a regional population survey of 1966 halves, and pehaps the 1966-"S" halves can now be discerned. On the US east coast probably fewer than 1 in 1000 1966 halves garnered from circulation was minted in San Fran, but on the west coast San Fran halves would be relatively much more common, perhaps 1 in 200. Interesting data.

Thanks for those numbers, Condor. I think the Kennedy SF mintage figures are for the SMS coins, right? If so, I'm seeing higher numbers for SF minted halves in 65-67. Where did you find the figures for SF halves? Just curious.

Thanks for the figures, Conder. That answers my question from a few days ago. Quote:

Interesting data. Neat idea. I'd be interested to see if someone could confidently attribute certain die markers to San Francisco, but it seems like a bit of a long shot. Quote:

From what I've read in the Mint Reports, the only 65-67 business strike half dollars were produced in Denver. If SF produced a few in 65 and 66, I would be interested in seeing where those numbers are recorded. I'm working on a presentation for my local club about this very subject and it would be a great reference.

So, if the mints did not include mint marks on their coins in 1966, how do you differentiate the Denver coins from the San Francisco coins?

The lack of mint marks prevented coins from being "hoarded" by coin collectors during a coin shortage. Collectors now only needed one coin, not three. They were also robbed of being able to buy distinct proof and uncirculated mint sets. The coinage act of 1965 might be seen as anti-collector, but it was really all about the shortages created from hoarding silver. The removal of mint marks was not originally part of the proposed legislation.

Those 813 million 1967-"S" cents represent the largest quantity of any coin denomination made in a single year by the San Francisco mint.
