Last weekend while going through the one dollar foreign coin bin I found a coin from a place I thought was cool. It was a Ten New Pence from the Isle of Man. Fast forward a week. I had bought some two by twos at the shop today which was its final day of business. As I was about to put the coin in the two by two, I noticed some hub doubling in the letters on the reverse. I tried to look it up but could not find any info. Any thoughts?
I'm not sure. I think it is a proof coin. You might be on to some thing @paddyman98 . Thanks for the reply!
I do not see any added value, as there is virtually no interest in well nigh invisible manufacturing effects among British and European collectors and the US fans for such things are normally only interested in US coins.
I imagine that this is a 1975 a circulation ten pence. A mis-strike on the 1975's thinner smaller flan is recorded. The coin itself is common with a possible mintage of 1,454,265. I do not believe Pobjoy minted proofs for this year and denomination. Please post the obverse photo. If it is a 1972-1974 its scarce and was struck as a token piece with a mintage of 1,000.
I forgot about the 1971 issue. The Royal Mint issued these - Pobjoy started minting them up in 1972. The circulating 1971 10p has a mintage of 100,000. Proofs??? I'd have to say yes to doubling.
On second thought - Not sure about the doubling. I was looking at my Pobjoy issues and not the Royal Mint issue (1971). While I do not have a 10p, my other 1971 issues have similar strikes.
I believe you will find that the "doubling" on both the 1971 10 pence and 5 pence is only the style of font chosen for artistic reasons. Yours is proof (10,000 mintage) but a little banged up.
