Double Struck 25¢ Check it out-has me baffled!

Dog97

This was on eBay as a double struck off center and I'm thinking yeah yeah right probably machine doubling but it looks really severe for MD so I bought it. Don't know about the off center part but it is DS & looks like some kind of partial collar error. Check the rim. Comments?

Definitely a cool double-strike! I have a few, but none have been that dramatic.

The rim is what has me baffled-I never seen one quite like that. Smooth on the 9k side & ½ reeded on the 3k side.

I knew when I came into this thread that if Dog didn't know what happened, how in the world would I know?

The rim is strange indeed. Can't think of an explanation.

I've seen the same type of rim on coins that have been in a bezile (Necklace), I have no doubt that if you say DS, then it is DS, believe me, to hear you say your Baffled about an error coin not to mention a 97 is beyond my comprehention but what about this...Is it a possible struck through? From the pic it looks to me like the nose is cut short, possibly something on the nose caused severe MD. As for the rim, maybe on teh wrong stock, or thined stock somewhere between the quarter and the dime stock, causing less metal flow into the rim...which would NOT explain why it is on only the one side....I don't know, go t me too...lol. I'm just shooting fish in a barrel here...lol.

Thanks for sharing, always interesting to see new errors.

I always think that too when he posts a thread ask.``whats this``.
Its the professor asking a freshmen for help? Or, a clever teaching tactic.

BTW Hows that Crow taste? hehe
What does that mean?......?.......
werent you one of the ones denounceing any DSs carried a premium?
Hmmmm??
Sorry man.I,m not calling you a hypocrite.I,m joking.

Oh...you got some down feathers stuck on your teeth...

hehehee

Anyway...Your the Bomb Dog.



Ray.How ya doing?Thought you were shipped off.You tell em you were gay finally?

Dog,

Is the reverse normal, or was there part of the web stuck under the edge of the planchet? How is the narrow edge?

Dog97

No, Cam40, not a trick post. Just a weird rim.
The 1st strike is the main strike then the coin or the obv die shifted slightly for the second strike. Since the planchet metal had already filled the dies from the first strike the 2nd strike only had enough planchet metal left to create the low secondary design that looks like MD. The rev is pretty normal except for slight "doubling" in some letters.
The edge picts pretty much sums up what's happening there. The copper layer in 2nd pict is wider than the reeded area. Some kind of collar error I guess.

Question.
When did the Mint employ the single-squeeze method of coin production.

Thats the modern method now being used I think.
That also would eliminate to possiblity of any true double strikes wouldnt it?

Or maybe if was made on the new equipment and the hammer die just shifted slightly during the end phase of the squeeze?

My theory is the planchet was struck while slightly off the anvil die (maybe tilted just a hair off level and resting up against one side of the collar). That would explain why the collar did not properly fill with the metal flow from the planchet being struck by the hammer die. The planchet could have then seated itself correctly with the impact of the blow which could create the doubling effect you see. One way to test this theory would be to check and see if the reeding is either full (normal) on the side opposite the smooth edge of the coin or even a bit heavier on the opposite and diametrically opposed side of the partial reeding. That would tend to substantiate the off-level position of the planchet when being struck. Of course, I wasn't there when it happened, but the progression seems logical to me.

Cam40-
In 97 for quarters but I don't know when in 97.
You're thinking doubled dies-this thing is double struck.
danglen-
You can see from the picts that the reeds are weak, almost smooth on 1 side and only ½ width on the other and do not indicate a tilted collar, which is what you describe. They pretty much show 360 degrees of rim.
I've never seen an edge that was full collar on 1 side and partial on the other and not be tilted.

Dog,

I've seen a lot of funny things come out of the mint, but the minting process always remains the same. If a planchet is seated correctly on the anvil die, and tha hammer die strikes it correctly and with the amount of pressure required, the metal will flow into all the appropriate cavities on all three dies and produce a "normal" coin.

If the collar is broken, the resulting strike will produce a boadstruck coin, which is not the case here because the rims on the coin are well defined. My question would be, and I have to ask because I have not seen the entire periphery of the coin, whether the reeded portion of the coin is the same width around the entire perimeter of the coin. I'm not sure what portion of the edges you are showing, but I'm GUESSING that it is not. And if this is the case, then a tilted planchet would produce a coin like the one you are showing in your images.

As Bill Fivaz is fond of saying, "I can't say with certainty, because I wasn't there". And I certainly wouldn't bet the farm on the correctness of my theory, but until somebody comes up with a more plausible theory, I have to go with what I see.

Regardless of the cause, it's still a neat error.
