Coloured Coronation/Poppy $2

purplepennyhunter · August 02, 2013, 08:09:46 PM

This is not my idea so I can't take the credit. But how (in the process) is the purple paint applied. Is it possible to get a coin with purple on the obverse?? Food for thought.....

The coin would have to be flipped in the pad printing process either error , mint sport or God forbid some silly bugger pad printing "Post Mint".
I do know that the area pad printed on a standard coin has a different finish to the rest of the coin.
I am unsure if the ink would stick to the uneven surface on the obverse properly.
Are we talking the "C" mintmark or the RSL coin here?

"Show and Tell" time

Think about the coronation purple coin. When in the process is the paint applied. Is someone standing there turning all the coins the right way up going into the colouring machine? Don't think so. I'm not sure either that it's a pad printing process. I don't know.

it's the underpants gnomes
they come out late at night and after hiding the underpants so that you can't find them in the morning when you're getting dressed for work

...... they also paint the coronation coins purple

I don't know either PP, But what an interesting question :good:

Maybe it's done directly after the coin is stamped and they should know its orientation (the obverse and reverse dies have a defined slot in the press I assume).

Ewwwww.. I just got this mental image of RG going to work commando.... I may never recover from this... :dodgy:

Anyways...

Here's how the Perth Mint does their CMYK process:
http://blog.perthmint.com.au/2011/06/24/how-does-the-perth-mint-colour-coins/

RAM would be similar but higher-speed machinery, using only a couple of colours at this stage (purple and clear). Presumably there is an automatic coin flipper as well. No way will there be any manual handling of millions of coins. If there were examples printed on the wrong side, we would have seen them by now, surely?

But it does beg the question of bag marks under the paint. We've seen what a hard life coins lead from the moment of striking, and the lack of quality control elsewhere wouldn't seem to indicate any gentler handling of these, would it?

Oh, and why not just wander down to the mint and have a look?

I would love to mate but the only time I am in perth I am working 12-14 hrs a day ( The last ANDA Show attendance screwed me up for a couple of days) Night Shift.
Otherwise I will travel there from home to get on a plane to other destinations for work.
I had about 80 days off last year (including Weekends) at intervals of 1-3 days at a time, Mrs Trout understands my love for coins , But that would turn to mud if I decided to use one of my breaks just to see how the pad printing process works :ok:

They would want to speed up that process. It's going to take a while to do 2 million.

I'm not goin there :mocking: but I know he'll get in big trouble if there's not enough wood there to stoke the fire..and that's firewood for the fire people, you lot make me wonder :laugh2:

I did actually mean RAM, not PM. We've seen PM's gear, which is only used for small runs. RAM went with high-speed equipment so they could churn out millions. They tested it with the poppies, went into full production with coronations, and will likely ramp it up in future. That machinery is not insubstantial, and should be clearly identifiable from the public gallery, just like the robot they installed a few years back. There might even be a display set up, or somebody willing to answer questions. :angel:
