  1. It is a die clash, in fact the dies have clashed twice with a slight offset between clashes.
  2. And since the farthing and six pence were about the same size and had basically the same obv, they could be plated to pass as sixpence. It may seem trival, but it was probably worth it. (Think about the trouble people went to in the US to grind down the diameter of cent to use them as dimes in vending machines.)
  3. Nope. The center layer of the 40% silver halves was 20% silver 80% copper, the center layer of the copper nickel clad coins is 100% copper. (The unusually dark center layer on the OP coin tells me it is almost certainly the 20/80 composition.) Ratzie, due to the mint tolerances on the weight (+/- .400 grams) a 40% silver half can weigh anywhere between 11.1 grams and 11.9 grams and still be in tolerance. Since they were not rolling the clad strip at the mint there would not have been clad stip the proper thickness for a half dollar. If half dollar blancj were punched from clad stock it would have had to have been either dime or quarter stock and the weight would be much lower. I believe a half dollar on quarter stock weighs around 10.8 grams.
  4. Satin finish, NO. Proof finish, Yes. Accented hair, No.
  5. No they are all 35% silver. Sound is not a very good diagnostic tool. Even with the same composition it can vary with the thickness (weight), force of strike can have an effect, plus the human ear is NOT a very precise instrument. Adding to the problem with the war nickels is the fact that they a plagued with lamination problems which can cause changes in the sound or even eliminate the ring entirely.. And the laminations do not have to be visible on the surface of the coin. Internal flaws can cause these problems. A ring test can be suggestive, but should never be considered to be conclusive.
  6. The one on the right is a 1963 proof and did not come out of a 1965 SMS.
  7. Probably some shenanigans inside the mint considering this was was a proof only issue. Since the strike is sharp this would have had to have been done with two anvil dies. I'm not sure due to clearances whether or not you could remove the coin from the press without assistance in such a case. (If you had two hammer dies it would definitely need assistance because the hammer die in the anvil position would not be able to eject the coin from the collar.)
  8. I think everyone is missing what he is asking about. He want to know why the center of the D is filled instead of being hollow like a normal D. On the die the letter is incuse or sunk into the surface of the die. That creates a little "post" in the center of the D that creates the hollow center of the D on the coin. If that post chips off the result is a D that has the outer shape, but the center of the D is just featureless lump. Technically it isn't a mint error, it is a die stage and clogged" mintmarks like this are fairly common so there is no premium value.
  9. Don't know what it is made of, but it is definitely a fake double eagle.
  10. If the object doing the gouging does not make the gouge in one smooth continuous movement it will show a repeating pattern like that as it hesitates, starts, hesitates, starts etc. Every time the gouging object hesitates for an instant a new ridge line is created in the groove.
  11. They sold Jefferson Nickel rolls in 2003, 04, and 05. They also sold cent rolls in 2008, last of the Memorials.
  12. And it may not "look" acid soaked, but it is.
  13. Trying to compare thickness of a planchet with a struck coin won't tell you much because the thickness of the coin is a function of the strength of the strike, and you would expect the thickness of the coin, as measured at the rim, to be thicker than the planchet. So the planchet being thinner would be normal. As to the diameter, the planchet after having the edge upset WOULD be smaller in diameter than the finished coin. This allows the planchet to drop easily into the coining chamber, and the planchet expands outward during the striking to the finished size as set by the diameter of the hole in the collar.
  14. It is good enough to know that you DON'T have an error coin. US coins are struck with "coin orientation" the obverse and reverse are upside down with respect to each other. Canadian coins are struck with "medal orientation" both sides are oriented upright with respect to each other. Your mirror picture shows that both sides are upright, the correct orientation for Canada.
