Only I can lose money by dumping coins from a slot machine!
Anyway, googling for specs I see:
40% halves(from coinfacts.com):
Diameter: ą31 millimeters
Weight: ą178 grains (ą11.5 grams) (ą11.3 grams for clad)
1943 - Australian Penny(from an eBay seller):
Size: 30.8 mm
Weight: 9.45 grams
I'm not sure how accurate slots or coinstars are, but the weight is off
a bit for the Aussie penny. Not sure on the thickness of the two coins.
At least they are selling for over 50 cents so I made a few cents in the
slots for once LOL.
Google got really slow this weekend, google usually doesn't lag that
far behind, but it has happen a few times this year. What ever problem
was it is fixed now!
