Large Shilling

nah - they had them way over the back
a coin club member pointed it out to me
we did ask if we could buy 'those coins over there'
just got a chuckle and the melting pot fib

How does a Mint Your Own work?  Does a RAM employee place the coin to be struck in the machine and retrieve it after the customer has somehow caused it to be struck?

[robbiegal]

MYO- money in slot - coin is pressed and automatically dispensed \untouched by human hands

the mobile mint at the show/s
employee places the coin into the mobile press - spins and presses the coin
then they remove it, inspect it and place it in the capsule/holder and hand to the customer

they get the chance to check out the coin

when I watched them do the bluebell ones they had a close up screen playing so that you could see the whole process

here are a couple of  the purple penny blogs with photos of the process - it is the mint employee putting the coin in place and the customer about to push the press button

Thank you, robbiegal.  This discussion brought the misplaced B counterstamp on that dollar we were talking about in another thread to mind.

had a chat to Tony and another ex mintie and agreed
either a halfpenny collar or possibly the PNG 1929 (?) penny collar - the one year where the penny was smaller than later issues
as the Melbourne mint only made PNG (TNG) currency other than aussie coins and that may have been a long shot by 1961 but that particular penny was small

yes, they should have been selected out re-melted down but it may have been possible that they were made without the error being picked up before the coins were mixed in for distribution

Tony didn't think that the small cud on Emu's coin would necessarily mean that it was from a different batch

it is a mystery and neither man thought that it was mint mischief - just a production error,  which for Melbourne was not common at all

anyways, they liked my coin and reckoned that it is a great example of an fairly rare error

Production errors were pretty common at Melbourne, heaps of lamination errors, clips to triple clips, poor hubbing (legend doubling, double nosed queen etc), cracked dies, rusty dies, high lips etc.
It is good they stuffed up, it gets us variety and error collectors drooling.

[robbiegal]

well, Marks' recent 1959 Halfpenny M error is testament to that!

Any chance of an image of the edge, in general this will tell you if a collar has been used.

Really faint milling??? Hmmm...

[Cobwebs]

A reasonably square edge, this usually suggests a collar was used.
Any faint lines on the edge could be the result of the coin being pushed out of the (plain) collar. These lines can be seen on 50c coins now and again.

If a wrong collar die was used, it raises the question, is it a broadstrike.

Have you measured the diameter?

No. It would be a mule.

here is my attempt at measuring and matching against a halfpenny & another shilling
hope that the pictures say a million words (*giggle*)

Great pics RG!
