simple enough this changes each gold coin to the realistic weight of a gold coin
real gold coins about an 1oz so i have converted it to and changed it for skyrim so now it is the real weight for gold coins
they will still show up in the inventory as 0 because each coin is less then 1lbs
each coin has a weight of 0.0625lbs or 1oz
This may be a little much for ppl that want to carry thousands and thousands of gold such as 53,987 at one time but this is a realistic weight for a gold coin and if you want your gold to have weight you shouldnt have that much on you anyways in my opinion

i would also recommend the bank of skyrim mod for more immersion and use of your money
