Proof planchet for business strike?

I was wondering if there has ever been, or any info on, proof planchets being used for business struck coins? Is there even a way to tell?

Now I'm not talking about the dies but the planchets themselves.

Any ideas?

Thanks,

Michael

Several off-center business strikes on proof planchets are known.

 

I assume you're talking about planchets where the proof is a different material than the business strike? I was just thinking that for like a penny or nickel, there is nothing special about the planchet is there? I know they polish the dies but they don't polish the blanchet do they?

 

tsk,

The planchets for business strike coins and proof coins are the same materialwise with the exception of the Dime, Quarter and Half Dollar for the Silver Proof Sets! Yes, Proof coin planchets are exceptional compared to Business Strike coin planchets as they are prepared somewhat different and receive a high polishing before being struck into coins.

Proof planchets have a slightly dimpled surface from the steel pellets they're tumbled with.

 

My thought stems from some highly reflective Lincolns I've come across lately. Since we know that San Francisco has sent dies to the other mints, why not planchets? Does this sound logical, or far fetched?

I know my coins are probably not proof planchets with a business strike but it got me thinking if it was possible. So thanks for the input. Man I love this place!

Happy hunting,

Michael

 

These highly reflective cents are common. They're just business strikes on conventional planchets. Proof cent planchets are presumably identical to business strike planchets because cent planchets are not cleaned, tumbled, annealed, burnished, or subjected to any further treatment after plating. That would damage the thin plating.
