Dimes struck on quarter stock are much tougher to find. The thickness tended to cause them to jam counters and they were quickly weeded out.

Recently acquired a 1997 P Kennedy half dollar on a thin underweight planchet stock of 10.96 grams. So its on a thin planchet with full reeding and XRF analysis indicated a copper/nickel alloy. The entire rim area is weak. But it has the trait marks of your examples.

Further comments are appreciated.

10.96 grams is within tolerance range. 11.34 +/- .454 grams That gives 10.89 to 11.79 grams.
