[QUOTE="Pickin and Grinin, post: 3431002, member: 73995"]Burnishing is usually used on proof and special release coins. I believe they started burnishing some planchets used for business strikes, but this wasn't until the mid to late eighty's, and I believe restricted to the Kennedy Half dollars. I am just wondering how a steel ball that is meant to polish or create a unique finish. Could possibly attach itself to a planchet and make it to the coining chamber. If you think about it, it is impossible for that to happen.[/QUOTE]
