Malaysia Bunga Raya Series 1991 $1.00 With Double Curved Clip Planchet Errors


How Double Curved Clips Are Made 

Please take a look at the diagram above to give you an idea of how these errors occur. Typically coin blanks are punched from a metal strip in rows. The rows are usually offset from each other (like the courses of bricks on a house) to more fully utilize the metal in the strip. In the example above the first row of blanks has been punched out correctly. However, for due to some material feeding fault or machine error the metal strip has moved from where it should have been punched so that coin blank 3 is punched out of an area that already had coin blanks 1 and 2 punched from it. This results in two curved clips on coin blank 3.

These errors are a lot more unusual than the single curved clip coin errors.I've only seen less then 5 pieces of double clip errors in two years! I'd recommend picking them up where you can.
