What do you make of this one??? Magnet picks up 1966 half dollar?

Strange.

Interesting link.

 

I am back to my original thoughts. If some one dropped something (a paper clip?, staples?, screw? etc.) into the copper while they were rolling it, once it was clad, there would be absolutely no way to detect it save the magnet. Out of all the clad coins they have made, I would find it extremely unlikely that nothing like this has ever happened.

 

If this is one of the coins in the link provided by TwoSon then you have yourself a $15 half dollar.

 

It's a miracle.

 

nickel is non-ferrous, therefore also not magnetic

 

Pure nickel is magnetic. Nickel alloys generally aren't magnetic, except nickel alloys of iron or cobalt.

Some older Canadian nickels (I don't know the years) were mostly nickel and are magnetic.

 

Alnico magnets are some of the strongest out there. They are Aluminum, nickel, and cobalt

 

Are the Philippine 50 sentimos (1967) attracted to magnets? Perhaps this was a trial run on the nickel-copper-zinc planchets used for the 1967 production of said coins at the U.S. Mint? Or perhaps some other alloy test for use in 50 sentimos or US half dollars?

There were a number of trials made on Philippine coin in 1966 and 1967. Perhaps this is a test planchet that got left in the press when half dollar production started?

 

any news on what it may be?
