Question/observation regarding unequal weight.

    With all the talk of fake silver around, i weighed 4 different one ounce lunars and got 4 different weights.

    Rabbit: 31.65 g
    Ox: 31.64 g
    Dragon: 31.36 g
    Tiger: 31.72 g

    Perth Mint states that minimum weight should be 31.135 g.

    Whilst they all pass the minimum, there is a significant difference of approx 0.3 g between the dragon and the other 3. Anyone know why?

    Also do your dragons weigh less when measured against other lunars?

    Were they still in their capsules when you weighed them?

    Nope. Got them from a reputable dealer though. The difference in weight though is puzzling.

    Byron, the lunars I sold you are kosher.
    I don't think any of the the 1oz Perth Mint bullion coins are right on the dot at 31.10 grams
    They usually have a slight remedy allowance of up to 0.5 grams
    Not sure why the Perth Mint is so generous giving you up to 0.62 grams extra with the tiger coin. :D

    I never doubted their authenticity or your integrity Steve. You're a good, honest dealer and i would highly recommend you to anyone.

    I'm just curious as to why there is a difference in weight mainly between the dragon and the others. As the dragons were bound to be so popular, maybe Perth Mint trimmed down their remedy allowance.

    Most likely this is also just a one off with my coins and not other people's. I also messaged Bron as 1for1 suggested and urged him to tell us more about this weight allowance. Hopefully he will reply.

    Our technical specs for 1oz silver coin are:

    Maximum diameter 40.6 mm
    Maximum thickness 4.0 mm
    Standard weight 31.635 g
    Allowable variation +/- 0.5 g

    There is a trade off on spending more money on production processes to reduce the variance (which would save us money in excess metal given away) vs the cost of those extra processes.
