While I do like many oddities I would have to say many errors are my favorite. This is my first off metal strike. I find these to be very unique and collectable. The original 1971 10 New Pence is copper-nickel 11.3g and is shown here as an example. My coin is 1971 10 new pence possibly bronze weighing 9.92g as seen below.
Neat.. Do you plan to send it in for attribution? What other coin would that planchet been created for?
Very interesting, looks like the coin saw use for sure. From the size of the coin and the weight you gave, if it is bronze, it is likely struck on a planchet for a Jordan 10 fils.
Paddy, I have a lot of research to do. Not sure what the planchet could have been for. I will send it in to be graded and attributed. But I will do a little research myself as well.
It is possible as the British minted these in 1970 and a planchet was left over as they didnt mint them in 1971. They were 28mm and the 10 pence slightly bigger and would explain the missing rim area. The weight would be about accurate as well as these were 10g
I doubt the environmental damage and have quite a few OMS myself from this era. Was the OP coin from the London Coins auction?
Don't know that they would "rubber-stamp" the exact origin - IMO the usual is to simply authenticate as a Royal Mint product and then general comment as to OMS status.
Although some like the slabbing (me on occasion), here are a couple that are related. First is an OMS 1975 10P in decent preservation. Second is an OMS 1963 Halfcrown struck on a Penny planchet (erroneously described as H.penny) As you see, they will not venture out as far as to certifying origins and can make mistakes at that! The second would nowadays be prohibitively expensive...
Those are very beautiful especially the first. These are the pictures I took in hand. It is at NGC for processing.
Ah, nice picture. Do keep us posted as to the grade, I wonder for which coin was this planchet intended. I always felt this to be a beautiful design.
I truly believe the 1970 Jordan 10 Fil. I cant find any other coin at 28mm and similar weight. From the research it was not made in 71 only 70. My guess would be some planchets were not cleaned out before they put the 2 Pence back into minting in 71. The new pence is 28.5mm so not much size difference. It also weighed 10g and this coin is 9.93g with wear or tolerance I would think this would be the only rational choice.
