Title: $2 error coin.
Post by: accumulator on April 06, 2014, 10:51:34 AM
Struck on a damaged planchet ?
To me it looks like the damage on the reverse may have been the reason why the obverse was mistruck.
What do you think ?

Struck on an incomplete planchet.  Planchet looks incomplete because it "split" and separated prior to the coin being struck.  Very cool indeed.

Probably because of the rev. That obverse rim looks to be much higher than it should be, and you would never notice wear on that reverse.

Yeah, very nice find... you know there's a good home for it here, right? :angel:

:shok: dodgy seller or clueless? Hopefully the shed jobs brought the price down?

I really think the seller has no idea about error coin & they pretty much said as much in the ad.

Now here is the really good interest part ,the coin only weighs 4.6 grams instead of the 6.6 it should.
So a fair bit of the planchet has split off before the minting.
The coin does have a plump look about it on the thick side of the planchet,it thicker on one side than it is on the other, quite noticeably.

Wow.. a third of it is mjssing???? I'm shocked. :shok:

OK, lets assume the planchet ended up wedge-shaped. It seems reasonable to assume a deeper strike than normal due to the thinner metal. Metal would flow from the thick end to the thin. though not enough to fill the torn surface. The result as we can see is a really deep, plump look at one end, and a virtually untouched obverse at the other.

Now I'm curious to know what the thickness of the coin is, field to field, as compared to a normal planchet. I'd think not 33% thinner.. maybe 20-25%?

OK,i've spent the last hour looking for my calipers with no joy,goddammit.
Anyway here is 3 pics that show the comparison with a normal $2 coin,pretty well i think.

Thick side of the error closest to the normal $2

Regardless of the outcome of the question, it is a darn good find if you ask me.   Congratulations.

I was feeling suspicious that the planchet may be a foreigne one that has made it into the blanks bag as it may have come in on weight or size in the sorting lot

:agreed: Excellent work!

See, Mark's is more what I was expecting to see from such a flaw. The entire obverse is formed, albeit not fully struck.

I know which one I'd rather have, given a choice... ;)
