This is in the 2011 Charlton on p. 291..Haxby PC59-361..with dies 36+E37 It's a great example of this known RP 9,.. and die chip.. I've seen this variety before,..but this is the first time that I've seen this die chip in such a perfectly round state.. Can the cent experts here explain how a die chip can come out so perfectly raised and round..? Thanks....       |

MMMM would that be the drill hole to stop the crack?

That's what it looks like to me ... a shallow drill to stop the crack and not a die chip.

That's interesting, very small and very round, I see what you mean.
The crack at the front of the queen that was likely trying to stop? but don't see what the poster above means by it being by Regina?
wonder how long it worked for?

the dot after Regina is on every penny from this year, the poster means below the neck.

I was very tired when I made my post and wasn't thinking clearly .. of course every Vicky had that "dot" between Canada and Regina. I guess it comes with old age .. I'm 70 now. The teeny one directly under the Queen's neck could be from a rust pit in the die and not a chip.

The Charlton pics show the small dot below the bust on this RP 9 with that die paring..(obv 36 on p.291) The Haxby site does not mention the dot below the bust,..but does show the same fine die crack leading up to the left side of the bust on the die 36. The Haxby obv 36 photos do not include the bottom of the bust so it might still be on the coin in his reference pics.. Quote:
MMMM would that be the drill hole to stop the crack? Now a drill hole in a metal plate is often used to stop die crack progression,..but if you drill a small round indentation in a die "to add a bead on the coins surface",..I don't know how a bead would stop a die crack. Are there any metallurgists how there with their professional view on this..? .......and..... So..do all obv 36's have the small round bead as showing in my above pics..?..(more pics coming up..) . .

I too fell for the one @ REGINA, without thinking beyond my nose. Even studied it for quite a while and wrote a big reply, I deleted it after a dozen or so yawns lol.
I agree with Okie on it being a rust pit.

I think it is a die chip. I would think that to drill into a hardened coin die, you would first have to anneal it, then drill, then harden it again. That's a lot of work. Also the hole would have to be drilled as deep as the crack to have any effect, I think.
I have an example of this one I will try to get a photograph of tonight and post it for you DEVLEC.
Jim does mention the "bead" in his description of die state 4 on the page for obverse 36.

When you are working with most metals, especially hardened ones, you get many surface cracks that are very very shallow and then turn into deep, all-the-way through cracks. We had to work with that stuck all the time with shipboard equipment. Hardened shipboard ballistic steel was the worst .. it might stop shells/bullets, but it sure cracks easy with the constant flexing/pounding that ships take.

...and here is another 361 ..also without the round dot..and therefore at an early state as the d/c's in the "R" of Victoria have just started..and the "R" of Regina possibly has just started.. Interesting examples to see here... ..but what do we make of that nice round dot..?.. A die chip,....or just added at some point..?      . . Edited by DEVLEC
