Coinstar vs. the Kitchen Scale

[hattifattener]

How much was in those change jars on top of the fridge? I weighed the coins and then ran them through the counting machine at QFC.

Coin Weight Mass ea. Est. by wt Coinstar Diff. Quarters 621 5.670 110 = $27.40

I feel like I need a shushing on the 'measure their length' bit too after the 'v-shaped groove' you're sliding things into.

You should drill a tiny hole in the fire lizard one and wear it as a pendant!

Now I'm thinking of other interesting, improbable ways of counting them. Immersing and measuring the volume. Pouring them out in a stream past a high-speed camera.

Laying them in a row and measuring its length.

Oh, you said interesting.

I'm trying to figure out some way of hitting the whole thing and measuring the frequency at which it rings, but that may be Too Interesting.

Vaporize them in a calorimeter? You'd have to do the Coinstar part first, though.

about ten years ago I realized my purse was awfully heavy and that might be why my shoulder was hurting. I looked in my purse and realized I had an awful lot of change floating around the bottom. so I took it to coin star and ended up with about $70. I did the math on the weight and it was just shy of 7lbs.

my current coin program funds my purchases on iTunes. I dump any coin change I get into the "ashtray" in my car. when it is full, I take it to coinstar and use the money to get an iTunes gift code. I did this two days ago and got about $16.50. takes two to three months to fill up the "ashtray" which I now dub "cointray".

Thank you, I was wondering! Sorry to have missed the 50-yen pieces, since I think I have all the other Japanese money (and will take it to get changed RSN, wish the money-changers at the airports had been open), but I'm glad you have the 20+-years-obsolete wonderful Australian 2p!
