I have a 1968 silver planchet clad in silver that's 2.56 grams and what appears to be struck with no collar around the die. You can make out the date with your eye and it's a little bit larger than a penny and just shy of a nickel in dia. And it's about half the thickness of a dime. It does have the reeds on the edges. I know there was a 1968 oddity like this one but without the collar error. I'm wondering if this was struck first then the error fixed and then the other one went through. I also know that there were three other examples from 1965 that were like this and sold for pretty good money I think like 9k or 12 k. If any one wants to take a stab at what they think I may or may not have please feel free to chime in thanks
