I came across this brochure that I acquired years ago and had just tucked away. It was put out by the American Bankers Association in 1965 to prepare the public for the new clad coinage.

Like nearly all publications addressing the changeover it tries to assure readers that the silver coins will not go up in value enough to justify saving them and that the hoarding of silver coins will not be cost-effective. Both the government and the banking industry stuck to the script by proclaiming that the older coins would circulate alongside the new pieces for many years to come. I recall from my own collecting experience that silver became increasingly scarce during 1966-67, and it disappeared nearly overnight after the period for redeeming silver certificates ended in mid-1968. These were my formative years in the hobby, and it was quite discouraging to have even the common coins from the 1950s-60s vanish.
