Is this a denticle imprint? Mum took this out of circulation the day after C-Day (Conversion Day). Except for a tiny nick on Her Majesty's face the coin is in excellent nick.

Looks like a reed hit from the edge of another coin to me.

Coin has at least 5 nicks on the queens face and the denticle pattern is as John1 calls it. Very common on larger silver coins such as the 50 cents and the crowns where one heavy coin falls onto another at the mint.

How do you tell the difference between a 'denticle imprint' and a 'reed hit from the edge of another coin'? Thanks

I believe they are the same. Just one of the many confusing terms our US cousins use to describe things

Could it be from a rim burr (dislodged) that was then turned into a "struck through".....would need coin in hand to tell if there is any metal movement, if yes then it's a reed hit...IMO....best of luck

Definitely PSD. It's a hit from a reeded edge from a coin.

From my understanding:reeds are on the edge of a coin and denticles are on the obv and or rev along the rim. On a reeded coin the reed edges are also on the edge of the rim,so when if hits another coin it leaves that jagged look. Denticles are protected by the rim,so if it hits a coin I do not see how it would leave just the jagged look without also leaving the impression of the rim.

You are correct.. However, in OZ it is described as Denticle Pattern. Meaning it looks like denticles but is, of course, caused by the reeding or milling from another coin hitting it.

Not that it matters but in the 60(almost) years I've been collecting Coins In Oz.it was always referred to as "reeding" but it may have been a Sydney 'thing'.
The most common egs. were of course the 1937/38 Crowns,the following Coin hitting the hot minted ones already in the Bucket/Bin.
I had an 1938 Crown where the entire Obv. was hammered with Reeding marks but it somehow made it out of the Mint/Banks,i'll throw up a Photo if I can find it.

This is getting confusing, and not trying to hijack the thread. I refer to the well known 1921 Halfpenny with supposed denticle pattern, which I've always had trouble coming to terms with. In this instance the anomaly certainly wasn't caused by edge milling as there is none.

Correct. This is on the die and hence it is described as denticle pattern because it looks like the denticles have clashed. So it would appear that anything resembling the denticles on the coin is called denticle pattern regardless of what caused it.

It should also be noted that the Royal Australian Mint describes our coins as having a Milled Edge and not a Reeded Edge.
