Precious metals bimetalic coins/tokens/medals "melt" value

Hi to all, browsing through my collection I came across that the bimetallic coins containing precious metals (gold/silver) don't have the metal value. I show some examples:

N#27541
N#27995
N#22695
N#32970
N#593
N#590
N#594
N#31382

I think it would be a great idea if it can be implemented to show the value/values of the  precious metal.

The problem is, as others have pointed out in other posts, determining the weight of each component since many times only the total weight is known. And if it is known like here N#593 it's only entered as free text, not a defined field that can be used.  Regardless, the idea is being tracked here: https://en.numista.com/forum/topic145684.html

Yes I completely agree probably all bimetallic/trimetalic coins should have a couple of optional field for each material, its purity and weight, if known of course.
