Be very careful with those completed Listing prices on eBay. They are not always correct and can be manipulated fairly easily.
I know the buyer of that coin & it is correct , the 2oz single key coins are off the planet price wise & you could include 2oz monkey & rooster singles if you could find one for sale with OMP.
