i know this probably elementary but i be ignorant. i have a georgia d quarter that appears to be stuck so hard that it has a larger than normal diameter with no apparent double dieing and high rims especially obverse. what is it called?.... also have a california p quater with missing reverse clad but can't find another example on the net: whats up with that???.... and is there any value to slighly off center, say about 10%, ie no part of er in liberty visible, kennedy 1985p, circulated. thanks

Speedy

If the larger quarter has reeding on the rim then I would say its damage...if it doesn't have reeding then it was struck outside the collar of the die IMO.
If you have a true missing clad layer then it would be worth a lot...it could be where someone took it off and damged it or it could be a copper wash...but please post photos of everything here in this thread.

The off center strike might have a little value but nothing $$$$

Excuse me, but don't this post belong in "error coins"?

Just asking.

I would say its 50%-50%--this is the US coin forum and they are US coins...

O.K. how about this? The post has enough in it to make it an error nomination so put 50% of the post in "error coins" forum. The rest of the post has to do with what is it worth, so put 50% in "whats it worth" forum. Leave the part about U.S. coin here in this forum. Just a suggestion!

the real question was: how did the georgia quarter come about, the others were " i also have these". the georgia quarter is apparently a die break of the collar die, as the reeding is complete. the break in the die was new enough that the reeding was maintained though the circumference not. thanks for all your input guys

If the coin has all its reeding then it was not struck out of collar. I suppose it could be a partial collar though. But you say it is a larger diameter than normal - just how much larger ?

ok, the reverse appears mostly normal. the obverse has high rims which barely oblilerates the top of the united states of america but not quarter dollar. there is a step down on the rim but no loss in reeding. the diameter is large enough to have the coin kicked out of a sorting machine. like i said it's collar die crack in it's infancy

mjorae

say collar die crack in it's infancy ten times really fast

cladking

I have seen pictures of these and your explanation seems consistent.

Can you account for why it appears to be struck unusually hard or is this it?

well, the obverse, because of it's large rim, makes the coin appear to be sunk into itself.... where the top of the united states of america is slightly obliberated, the rim is similiar to a 'railroad" strike or whatever, but on the flat surface not on the rim surface. i don't know what the order of striking is in minting but it would appear that the reverse was srtuck first, the crack occured, then the obverse was struck. i'll try to send pics.

Small round disks of metal are punched from a large flat strip of metal in the
blanking press. These are often referred to as type 1 planchets. These are
a little larger than the coin they are intended to make so that they can be stood
on end and forced between two spinning rolls. These rolls squeeze the coin down
to the proper diameter for minting. The planchets are now called type 2 planchets
after going through the upsetting machine. The purpose of upsetting is to bunch
up a little extra metal around the edge of the planchet so that the rim of the coin
can form during the strike.

Planchets go into large totes and transferred to the coining presses. The old style
press simply pushed a die downward into the planchet with the reverse die under-
neath. The metal acts like a fluid under the extreme pressure generated and flows
into the recesses of the two dies. There's the third die or collar which is there to
stop the metal from flowing outward.

Newer presses are actually horizontal and have four obverse and four reverse dies.
They strike at very high speed.

My understanding was that the older vertical presses were the ones that were the quad die presses operating at about 150 cycles per minute. The new horizontal striking Schuler presses are single die running at 750 cycles per minute.

Can you post a picture of your coin?

cladking

It's possible I'm confused. I'll see what I can find.

I do believe there are some vertical quad presses.
