Royal Mint Museum reply re 1989 Queen with 3 chins GB £1 coin

Received a reply from the Royal Mint Museum regarding My 1989 GB $1 coin with 3 chins on the queen. The 1806 double head penny as suggested by a CT member is indeed the work of a victorian trickster, No biggy but a nice addition to My error collection

I would ask if 'Chris' was the one making these determinations, because I wouldn't trust someone with that signature

really though, the pound is a great example of die chatter.

 

yeh i thought the same
Yours sincerely - Squiggle (I cant be arsed signing any more today)

 

So in effect machine doubling or in this case machine trebling according the Mint

 

Good question Im wondering how a coin with Die chatter would be graded is it machine doubling/trebling or would it have a higher eye appeal ?

 

It is treated just as valueless machine doubling/tripling. (Interesting to hear trebling used, I haven't heard that used in a while.)

You see this on older US large cents on occasion, sometimes it is very obvious

 

Cheers and valuless as expected back to th eye loupe for another few months Actually I was not comfortable using the phrase trebling on CT but its in the Royal Mint letter so Chris (the poor signee) is firmly responsible

 

Trebling ?? oops tripling

 

Trebling is a proper term as well. Often used more in legal context though

 

Yes, it’s correct just not something I hear nearly as often in American media as in Europe. It’s cool!
