Made an interesting find. I went to a bank to dump some quarters, dimes and zincs I had searched and while there asked them if they had any halves. They had 8 rolls plus some loose...so I took them all. Before I leave I usually weigh the half dollar rolls to check for any shortages (I've been burnt in the past and being short 1 or 2 halves in a roll does not make me happy). One of the rolls weighed 223.7 g which is below the 225 - 226 usual weight so I opened that roll at the bank thinking that there was something other than a usual half dollar...nope, there were 20 Kennedy halves...so I took them. Later at home I started to check that short weight roll in detail and what I found was a 1967 (40%) half that weighed only 9.7 g (should weigh 11.5 g). The coin is the thickness of a Quarter. It was a Half Dollar punched on Quarter thickness stock. I've heard that this occasionally does happen and is listed as a mint error, but what I don't understand is the error is on a 40% silver half...they didn't make 40% silver Quarters in 1967.
If anyone has any insight, I would appreciate your thoughts. Any idea of value?

I just came accross an article by Ken Potter of Numismatic News titled "Kennedy Struck on Quarter Stock"

| So does the coin look like it is silver? Maybe some left over silver roll for quarters got used? Sounds like this could be worth something - curious to see what you find out. |

Sounds like a half struck on "quarter stock", but as someone else asked- does it look silver? |

Yes, it does look like a silver half. A friend suggested it might be missing the copper portion of the clad 40% coins.
Not sure how to attach a pic to these messages. I do have a scanner and it puts scanned pics to My Pictures but how do I get it to attach here?

Does it sound silver or just make a "thud" when you drop it? |

| It most definitely has the silver ring. There is no sign of the copper clad on the edge that many of the 40% one's have. |

Flip it and listen for the Silver 40% ring.
If it sounds funny (like highroller's "thud" suggestion above), you may have a hollow "Magician's" coin. |
There's profit if you melt things!!

The coin appears to be solid and the weight (9.7g) is consistent with the reduced thickness of the coin (quarter thickness not the normal half thickness).

| Can you take obverse and reverse pictures of the coin out of the flip? Also a side shot compared to a quarter and a half. |

Pics follow as best as I could. I also took a micrometer and measured the thickness of the coins...2006 clad quarter .065; the subject coin .065; a normal half .085 (used a 1968). The subject coin is the center coin in the side view pic. Note: the quarter and the subject coin thickness were identical at 65/1000 of an inch whereby the normal half was 85/1000 of an inch.

I was not aware of this but evidentely the mint made 1964 90% silver dimes, quarters and halves for 3 years '64, 65' & 66' per Ken Potter so it is possible that this coin was made from a 90% quarter stock that may have been left over from the last '64 silver quarters made in 1966.

| I would think a 1967 1/2 on 90% silver quarter stock should be worth something. That is a pretty wild combination. |

| How much do you want for the coin? I would be interested in at least seeing it or buying it. |

I would guess that something was misplaced at the mint, and when someone was about to run a batch of hales, they picked up the left over quarter stock that was mixed in with the half stock.
The question is, how many were made before they realized something was wrong? And how many made it out the door?

This is the best way to get full value for it, should it turn out to indeed be a rare error. |

Wow! This is very interesting. Send it out to PCGS or some other grading company to see what they think. This could be a very very valuable error, and I wouldn't sell it until I got a professional opinion.
Let us know how this turns out! |

Have you tried ringing it? A 90% coin would give you a different tone than a 40%.
Has anyone done the math to calculate what a coin the diameter of a half dollar on quarter stock should weigh? Should be something like the ratio of the diameter of a normal half dollar to a normal quarter x the weight of a 90% quarter. You wouldn't even half to do any calculations using pi.. 3.141592653591 as close as I can remember off the top of my head.  |
If your percentages are low.. just sort more. If your percentages are high.. just sort more.

Following Hoard's logic:
Normal US 1/2 1.205 inches divided by
Normal US Quarter 0.955 inches
the 1/2 is 1.26 time larger X
Silver Quarter Weight: 6.25 grams
Equals expected weight of a quarter thickness 1/2 is 7.89 grams.
Actual weight of the coin is 9.7 g. Therefore maybe the calculation is faulty.

You have to calculate the difference in area...the outer inches would cover more area than the inner inches. A friend who was an engineer (now retired) calulated that the weight of this coin punched on 90% quarter should weigh a little less than 1.58 x the silver quarter weight. He came up with a weight of 9.8g which is very close to the 9.7g weight of the subject coin. At the local coin show yesterday I showed the coin to a few dealers who know error coins. All agreed that it should be graded and verified to obtain top dollar...some said PCGS, others said ANACS...I also got some names of individuals at Coin World and a grading expert in CA who evidently is the grader PCGS uses for high value coins. Pretty much all said it was something special. One dealer I know pretty well 1st offered me $5, then $25, then $50, then $75, then $150, then $500 over the 5 hours I was there...not sure how serious he was on the 2 higher offers. When I was leaving he came up to me and said he thought it may have a value in the $ 5 to 10 K range (my heart was really pounding with that statement). So far all the checking I have done points to this being what I think it is.
Ken Potter (Numismatic News) said it was a "nice find" but wondered why this error has not been identified before as he speculated that more should be out there. Mentioning this to one collector at the show who is very knowledgeable on the US Mint and their operations said that when the coins were silver their quality control was much tighter than now with the cheaper clad coins. He speculated that they probably would have caught the problem and stopped most of this error from getting out the door...so maybe very few were not caught and were released. This would at least partially explain why this error has not been identified before. Secondly he said that the 1941/42 dime errors were not identified for many years after they were released. There have been several clad 1971 Halves punched on quarter stock found.
Needless to say, this has to be pursued further. Meanwhile all of you should be checking any 1967 halves you may have. |

This would really upset me- he's basically admitting he tried to rip you off with his first offers. |

You're right...it does upset me as I've known this guy at least 3 years. |
