I'm looking for $1 horseshoe molds for trade, specifically Big Meadow and winnemucca chips.

The question is on the 50 cent chip. If you notice the top left is gold heavy hotstamp and the other two are silver hotstamp. Of the 6 or so of these I have, they are half and half gold and silver. Would this be a variation? Would it affect the value?

The star side of all of them is all gold hotstamp.
