I did a bit of searching and found a reference that said the US mint made 1 Colon coins in copper-nickel for Costa Rica (Philadelphia) and 50 cent coins in CU/NI for Liberia (San Francisco) in 1968. Specs are close to your coin. I did not find a reference to Denver mint though.

I'm in the "rolled thin" camp. No other coins of that era were 40% silver, so it must be an underweight half-dollar planchet.

Well the half dollars from 1965-1970-D were part silver stock. The normal quarter those years were just normal clad stock. So the edge will not show the copper layer those years.   So it has a normal planchet stock for that year.  |

So Coop, Do you think its just half stock rolled thinner than other stock. Is this considered a mint error?

Actually Silviosi, no one has definitively stated for sure this coin is struck on a thinly rolled planchet made for half dollars, on either forum. Also I'm trying to find out if this is a common occurrence and if its is considered a mint error. I have pulled approximately 8500 silver half dollars out of circulation and have searched over 2,070,000 half dollars and never seen one like this that may be struck on thin stock. I have pulled a 1971 struck on quarter stock. Again, my goal is to learn what happened, how rare are these types of verities, and if its considered a mint error. Thank you for your input though.

I know you was on other forums. What you have it is the only possibility for your coin. Those are not errors.

I agree with all of the above. Normal half dollar coin. Keep searching.  |

Merclover, its a half dollar for sure. Having CRHed over 2 mill halves myself, and collected thousands of silver halves there is not one that has this weight and size. Calling it normal would be a stretch. Yet I understand what you are trying to convey. Thank you for sharing your input.

Please explain these two very confusing conclusions. The rolls in 1968 was 1100 Ft. long for halves. The thin roll not "planchet" could be from core roll or from the cladding rolling. Those are partial and in general could be find in the begin or end of the rolls. Those are not errors. Happened on all denominations and all the years. This anomalies is frequent as the floating roof on Cents. I was and consult the year foreign coins struck and no one meet the closers parameters. Now I will put here the specs as per Mint and the 1965 Law: Quote:
3-layer composite coin. Outer cladding 800 parts
silver, 200 parts copper
bonded to a core approximately 209 parts silver and 791 parts copper. Thickness on edge = 2.18 mm, Diameter = 30.61, Weight = 11.500, Min, weight = 11.100 and Max. weight = 11.900, Reeds = 150 Those was the Halves 1965 till inclusive 1970. 1968 do not has P or S and only D (Denver) Hope this will help everyone.

There are many 40% silver half dollars in this weight range. They were undoubtedly struck on half dollar planchets derived from rolled-thin half dollar stock.
