What is the value of a Morgan mint copy of an 1849 20 dollar gold piece designed by James B Longacre that has a net weight 9074 troy pure gold?

This is a Copy of the the First $20 Gold coin but, just because it’s a copy doesn’t mean it’s not worth anything as this coins composition is made up of.100 copper and .900 GOLD for a net weight of .9074 Troy pure Gold! Adding it up .100 copper actually is the equivalent in Troy of .926 + .9074 would equal 1 Troy ounce but, since copper isn’t weighed this way total Gold weight is just shy of 1 Troy ounce by .926
