I was the tender age of 13 in 1965 . I noticed the difference but the collecting bug hadn't bitten yet .
I was 14 then and operated a weekend produce business. I sometimes made more than my father so helped with the house and collected Lincolns and Morgans for hobby. In 1964 my business ran on all silver coinage, but in 65-67 all the silver dimes and quarters disappeared and there were only 65 clads circulating. At the time I thought money became worthless and was disgusted with the whole money thing. By the time I was 15 I owned two business, attended high school, and took care of the house...no more time for coin collecting until the early 90s when I found time for collecting again. These were very changing times.
I was out of the hobby at the time, and it took a while for me to notice. My first reaction was "these feel a little cheap". Little did I realize how awful they'd turn out to be. At least clad coins hold up better than silver -- they seem to wear less quickly (although that may just be because they don't see as much use), and they don't tarnish as easily. Zincolns are an unmitigated disaster.
I was 9 at the time and as long as I could buy a comic book and a Mallow cup it didn't matter what the coin looked like or it's composition. I can't remember if my Mickey Mantle card was purchased with silver or clad.
I remember a coin article around that time which described Roman coinage and made the point that Rome declined even faster after it switched to clad type coinage.
That's funny! No laughing matter for the British Empire, though. It's decline went hand in hand with the move to 50% silver and then to copper-nickel. Maybe if they had stuck to sterling they'd still have colonies around the world...ya think?
Well I was four and my interest in coins didn't develop until the following year. But I do remember a lot of people upset with the trouble they had trying to use vending machines. Many of them would accept one type of coin or the other but few machines would accept both.
I had just gotten out of the Army and wasn't back into coins yet. Big mistake. I mustered out in 1964 from Alaska where the silver dollar circulated more than the paper dollar. Didn't have much money; the Army was only paying me $193/month BEFORE taxes. But I had saved up about $350. Just think if I had brought home that much in silver dollars at face.
Silver dollars were in the banks in SO CAL but no one wanted them until after they were all gone...I went to my local bank teller a few times a month in search of nicer Morgans. My friend's dad would buy the best finds for 2-3$ ea...a fine profit for me. Didn't realize what was about to happen with silver coinage.
At the ripe old age of 13, in Junior High, Red Book in hand, Coinage and Coins mag coming to the house, a member of a coin club, and able to find an occasional Indian cent, Barber series, Liberty standing, Franklin half, etc. this event was crushing as the silver material disappeared in a "New York minute" living on Long Island....
