Silver proof set composition of non-Ag coins

Heywood

Sorry if this is a dumb question to many,

Is there any difference between the non-silver coins in the Silver proof set and the same coins in the standard proof set?

Last time I compared the make up on the COA, they were the same.

They look the same, but maybe they have additional polish step on the blank planchet? are handled better (less)?


I break up the sets to put them in albums with my son, and before we get rid of the dupes, i wanted to make sure.


Thanks in advance

No difference at all although at one time, folks thought that the US Mint would put "Silver" Presidential Dollars in the 2007 Silver Set! Even the Redbook bought into it so therefore it was a surety!




NOT!

Metallic compositions and production processes are identical for the non-Silver coins in the Silver Proof set as with the regular Proof Set.

The big difference is that the silver coins in the Silver Proof Sets are 90% Silver and not the 40% Clad Silver as had been the case in 1971-1976.

I read somewhere that the cent planchets are given a heavier copper plating due to the multiple strikes they receive.

Modern cents, nickels, dimes, quarters and halves in proof sets still get only one strike. Some of the larger coins - mostly dollar size - and Mn alloy dollars get two or three.

RWB---I always thought proof coins got at least two strikes. When did this change? I would imagine that the proof coins that get only one strike are at least struck under higher pressure.
