The toning was there in the plastic box and saran wrap applied just before photo and posting and tape does not come in contact with coin only secures saran.
Yes, I know, but vapors from some adhesive tapes have been known to impart interesting color to silver coins even WITHOUT physical contact.
I like front and back also but in this case the mint mark is on reverse. I had a question in mind and did not use it so the error on obverse vs reverse. Think I'm too new to this to be on this site but was curious about Iridescent ring and web sites weren't helping I think I'm going to bow out. but may give you a good picture of front obverse.
In 1965, 1966, and 1967 the mint did not put mintmarks on its coins. In 1968, when the mint resumed putting mintmarks on coins, they made the decision to put all mintmarks on the obverse of coins for uniformity. If there is a coin shop in your area, I would buy a few cardboard holders or better yet plastic flips, to hold your coins (make sure the plastic flips are stiff, the soft ones contain PVC which is not good for coins and are for short term storage only). They do a good job protecting coins and are inexpensive. They are also available on eBay.
In most cases, I would agree with this. However, with this toning, this coin will probably grade out at MS65 or MS66. It's fairly ding-free. I have one not quite as pretty as this which is MS65. And if you don't think that toning can add two or even three grading points to a 1964 Kennedy half, I'm sorry, but you're just not keeping up.
Guess I'll put it in the safe and forget about it and maybe a Grandchild can deal with it later. I'm out of here.
I am just telling you what I see on E-Bay. Toning on the coin may bring a few more dollars, but, not much more. Raw Kennedy half dollars just don't bring big paydays. If you want to pay more than $10 for coins like this then you can be high bidder on most E-Bay auctions for this coin. Here is just one listing. There are hundreds just like this. https://www.ebay.com/itm/ONE-1-us-s...094620?hash=item5203cd265c:g:xrUAAOSwo4pYSFz1
I don't think you quite understand how obscene a price difference a bit of toning can have these days. Yes, those in that eBay listing are indeed $10 coins. Add some circular toning, and VOILA, you can instantly have a $40 coin. I'm not endorsing it, just reporting it.
