1 Ore 1936 Norway.

Certainly looks like a nice repunched 9 and and overdate to me. I can't decide what the under digit is but the 6 is over something (perhaps a high and low doubled 5)?

This is a tiny coin and dies were dated by hand so repunched digits are VERY common - the really interesting thing is that last digit.

Local Norwegian collectors in a very technical text should have identified this die variety. Krause is too general for this type of variety.

From what I see on the coin itself - I believe it is absolutely conclusive that the dies were individually dated by hand in that year. Nothing else would make any sense based on what you see.

The 9 is clearly double punched. If this was not a hand punched die - how did that happen. The last digit is even more clearly the result of some form of overpunching. There is no other was to produce this coin. PERIOD.

Of course, if every single 1936 one Ore issue was identical to this coin, you could speculate that the hubs themselves were double dated. I am forced to infer the existance of a hub because the mintage of over 6,000,000 coins is far too high in my experience to be the result of a single die pair.

When speculating about die life - size - strike pressure and metals involved are 3 components of what is essentially one interesting subject. This is a tiny die striking bronze - so I would anticipate die life for this coin to be several percentage points higher than a US penny of the same time period. I would expect that die life could be 4 times higher - roughly a square of the die radius to reflect pressure. Then the question becomes was ONE die pair used for the total production of any US bronze cent? The only single die pair variety I am familiar with is the 1955 double die. I have heard several statistics for how many were made BUT IT WAS A FULL RUN. Had it been caught during production the coins would have been destroyed. I have heard anywhere from 25,000 to 75,000 copies. The square of the radius ratio is under two. So I would believe there were likely 40 to 60 die pairs used in 1936 for the 1 Ore.
