it shows as 13 odd grams, yet my scale shows it as 5.04g. this is the new coinage not the older coinage, i will chwck the old 50c piece for weight when i find it but i bet its over 13g. yep, so maybe the new coinage needs its own thingy?
2006 was the year we switched to the smaller coins. The one we use now is 5g. If you have a 2006 50c coin of the larger size then I suggest you hold on to it. A few of the 2006 5c coins slipped into the hands of collectors and were selling online for as much as $300 each.
