NY Times, March 3rd 1968: An article talking about one of the periodic gold flare-ups of the 1960's that resulted in buyers/hoarders being willing to pay way above market prices for $20 Double Eagles, including Saints. DEs that normally sold for $50 were selling for $82 at Stacks, with other dealers reporting sales at just under $100. Gimbel's, the department store, had a coin department and they stopped selling coins during the run-up (as did Stack's) but before they stopped they were selling them for $75. The Stack referenced in the article is Benjamin Stack. I thought the discussion in the article towards the end talking about how holding the coins was NOT illegal based on the 1934 and 1954 law changes was interesting.
The reporter may have been out of his element citing those laws as an "OK" to hold gold coins. But we do know there was always a numismatist exemption since 1933, it just wasn't clearly enunciated for the common folk.
