100 years ago gold was quite simply panned for in river beds. Also it was mined by hand, miners used to seek a gold seam. Gold mines now use advanced mechanical tools to recover material that gold may be in. Gold can now be extracted from these materials by chemical methods.
Mined gold is typically not 100% pure when first extracted. It is usually combined with other minerals and metals such as silver, copper, and iron. To obtain pure gold, miners need to refine the raw material through processes like smelting and purification.
Of course there is a difference. 18k means that it isn't pure gold but an alloy. 24k equals about 100% so 18k gold is actually an alloy that contains 100/24*18 % (75%) gold. So you will of course get (25%) less money for 1 ounce of 18k than for 1 ounce of 24k gold.
24 carat gold is pure gold, meaning it is composed of 100% gold. It does not contain any other metals or impurities, making it the highest purity of gold available.
It is important to know how much gold is in jewelry. 24k is 100% pure gold, it means that all parts of it are made of gold.
The weight of gold can vary depending on the purity and size of the pieces. A common unit to measure gold is grams, so to determine the weight of 100 pieces of gold, you would need to know the weight of each individual piece and then multiply that by 100.

The value of 100 mils of gold clad depends on the current market price of gold and the specific item in question. "Mils" refers to the thickness of the gold layer, with 100 mils being equivalent to 0.1 inches, which is quite thick for a clad item. However, gold-clad items generally have a lower intrinsic value compared to solid gold due to the thin layer of gold over a base metal. If you're looking for a specific value, it would be best to check the current gold prices and consider the item’s condition and collector interest.

About 70,000 compared with about 40,000 in Japan.
It is just worth $100. Gold plating (or gold foil) adds so little gold that it usually isn't worth removing to melt down. These alterations were not done by the Treasury but were done by a private company and as such they've got very little collector value. Indeed, paper money collectors will view these notes as damaged and will decrease the value when compared to an unaltered example, although in this case it is just worth $100 either way.
Zakat on gold is 2.5% of the total weight of gold held for a full lunar year. So, for 100 grams of gold, you would calculate by multiplying 100 grams by 2.5%, which equals 2.5 grams of gold due for zakat.
