Title: Rim Strikethroughs
Post by: Fulvio on April 29, 2013, 01:13:21 PM
Here's a little find from just now that got me thinking...

(http://goo.gl/TU5Nn)

Its a 2005 20¢ with a die fill around the top of liz's head, just behind the crown. But seeing as how I like to work in the sun when its out, as I flipped the coin a flash of light hit the rim and revealed this largish strikethrough on the rim.

Obviously this coin is already a keeper. But now I'm wondering if such errors have any merit on their own. Does anyone even look for them? And if you do spot one, do you stash it away or junk it if there's nothing else going on with it?

to be quite honest , I rarely check the 3rd side of a coin :ok:

If I found that one,  I would be keeping ir.
I have not found any like that.

Is it a strikethrough or has the rim been chipped by something?

Its a strikethrough. PMD looks quite different, and there's always stray metal around the edges. This is just like when they strike through those lumps of black crud, but on the rim instead of the face.

I wouldnt keep a coin like that if i found it. I just couldnt convince myself it is a strikethrough and not PMD.

Easy way to convince yourself. Try and replicate it. Bet you can't. ;)

Sorry, but it looks like PMD to me too.  I enlarged the relevant part of the images and flipped one so both are sitting the same way and to me it appears that there is metal protruding above the level of the coin, just as there would be if the coin had been hit on the edge after minting.

I think I might try some trout style experiments. ...
It is hard to tell,  but I initially thought that there was a fair amount of missing metal without it being pushed somewhere else after having been minted.

With Accidental PMD, the metal will always be there somewhere. And Deliberate PMD will leave some kind of trace, such as tool marks. The amount missing from this hole is substantial, on a par with say a WW2 50¢ cud. As for some damage around the hole, well, in 8 years of circulation its picked up its fair share of battle scars.

At any rate, this was not about this particular coin. Its already a keeper anyway because of the die fill. Rather I was asking about attitudes towards Rim Strikethroughs in general, and I think I've got a pretty fair idea already. ;)
