Thinking about picking up a 10oz horse. It's $200. I could get a goat for about $10 less but I am assuming the horse is the more popular coin in the series. I was thinking that it was a decent price at about $40 over spot. Do the 10oz coins seem to go up in value or are not enough people into them? Was mainly just looking for something impressive looking for my son. The little one oz coins don't seem to impress him.
