Not too many vending machines take half dollars anymore.
And yes the Kennedy is within spec. Spec is 11.5 grams +/- .4 grams, so a 40% half that weighs anywhere from 11.1 to 11.9 grams is within spec. (When they went to clad, even 40%, the specs went down the tubes.)

I've managed to keep a driving range token in my possession for 4 months now, which is pretty amazing for me. So I figure I just might be able hang on to these coins.

Hmmmm...should weigh that token and see how it holds up over time compared to US clad coinage.

Here's an update: they haven't lost any weight yet. I do need to post the starting weights of the other coins that joined the game.

Very interesting experiment! Please keep us updated. Pictures would be nice too to see the wear/weight relation.

Results after 1 month:

1942: 12.448g (started 12.450g)
1967: 12.628g (started 12.630g)
1974: 12.268g (it started at this weight)

The scale weighs to 0.002g, so it took a month for 2 of them drop one blip. Which means they could have lost as little as 0.0001 grams and as much as 0.0029 grams.

It's gonna take a while to get measurable results.

Results as of May 3 (almost 3 months)

1942: 12.444g (started 12.450g)
1967: 12.626g (started 12.630g)
1974: 12.268g (it started at this weight)

The 90% silver coin is wearing the quickest, and the clad piece has no measurable weight loss.

Ain't that the truth. :)

Results on July 22 (5 months, 12 days)

1942: 12.440g (started 12.450g) No change from last month!
1967: 11.620g (started 11.630g)
1974: 11.264g (started at 11.268g)

No one noticed that the clads were 1 gram overweight for a few months.

Very interesting. I would have guessed they would have worn much faster. Have you noticed a great deal of wear since the start?
