It does look like toning, but I can see what you're talking about on the dime. If you have a local dealer (of some trustworthiness - I'm sure any number of people on this site could tell you some in your area), take them to him and let him give an opinion. If not, have them conserved, graded, and slabbed as a set. Better safe than sorry.
Took it to the dealer,he said it was oxidation and said it was worth 1200. I've seen just the halve's go for between 1200. and 2200. I've got other coins that are toning and they don't look like this at all. Guess try e-mailing NCG and try to find out how they treat oxidation.
Oxidation and toning are the same thing. It's just that it can take different forms, colors and looks. Something you might want to consider if you do not like the toning. Sell that set and buy another. There are a great many collectors who will pay substantial premiums for toned coins. Sometimes as much as 5 to 6 times book value. BTW - 1200 is about what most dealers would offer give or take - $1500 is retail. The toning can be removed - but it will cause the coins to lose some luster.
machine dbl. or dbl die? This is a kennedy half I found in my spare change jar is it m.d or d.d.?Thanks for any info.
Mechanical doubling. It's easy to recognize really - see how the lower area appears to be flat and shelf like ? But the edges of the upper area are rounded ? Well with a doubled die - both of these areas are rounded. That flat shelf is a dead giveaway.
While I'm at it and the camera's handy here's 3 more, missing clad? On 2 of them only the obv. is different, and the 3rd. both sides are this color. By the way thanks for d.d. help.
Based on the pics it looks like you have some toned coins. But it's hard to say for sure with pics. Look at the edges - quite often you can see all three layers on the edge but not always. But if you can - then you know for sure it's just toning. If you can't - then weigh the coins. If any of them are missing a clad layer it will weigh less than a standard quarter. If it does not - toning.
Was just wondering who would have a scale that goes that lite, My butcher is out, maybe the post office, they weigh letters, they probably would'nt mind, with only 800 people in this town they probably arn't exactly backlogged with work.Thanks.
