In a question you mentioned that the Indian Head and Lincoln cents were struck at the same time in 1909. Weren’t the Buffalo nickels and Jefferson nickels both struck in 1938?
As nearly as I can find out, the last Buffalo nickels were struck at Denver in early 1938, legally completing the 25-year requirement. Schlag’s design for the Jefferson nickel was not accepted until late July, so production would not have started until later in the year. Therefore, the two did not overlap. Denver switched even later in the year.
The San Francisco Assay Office struck coins with mintmarks 1968-1974, but have there been any of the other assay offices that struck coin?
San Francisco holds the distinction of having had two different official assay offices that struck coins, the only one to do so. The San Francisco Assay Office of Gold (its then-title) also struck gold $10, $20 and $50 coins in 1853-54.
Are there or aren’t there official records of four 1854-C gold dollars being struck? I don’t find them listed in the catalogs, but there are old references to them.
Walter Breen reports that the figure is the result of a dummy bookkeeping entry that was in turn the basis of the Mint reports listing them. The pieces eventually were identified and determined to be assay samples of the 1853-C dollars, stolen in transit to the Philadelphia Mint along with eight 1853-C half eagles.
When was the old New York Assay Office built?
The rather imposing five-story building was constructed in 1931-32 and went into operation in the latter part of 1932. It was built on the East River waterfront at what was known as “Old Slip.” The building was 142 by 195 feet and had a 160-foot smokestack to carry off the smelting fumes.
Did the Treasury issue any of the silver dollars that were in the vaults prior to the run in the 1960s?
Three million were released for Christmas in 1954, mostly coins of the 1880s. Uncirculated 1889 dollars that were found in the bags sold for $16. Other newspaper stories cited values to $17. One bank in Montana got a bag of 1,000 1893-CC dollars.
Wasn’t there a metal Great Seal set in the vestibule floor at the Denver Mint ?
Until 1961 the metal version was part of the floor, but by 1961 it had become so worn that it was replaced with a mosaic. The original was moved to the numismatic sales room for display.
