So, it is a Silver Dollar....which is what that actually has as a value.
I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment

Neither of those have the S$1. Does PCGS make up weather the coin gets an S$1 or a $1? Is there really a difference?

<< <i>i think they only use S$1 in cases where the composition could be clad or silver (see Ike series).....for commems that are understood to be silver its understood

They also used it for those years when the mint was producing both gold dollars and silver dollars (1849-1889).
