Gold ingots are heavier and much bigger than gold bullion which comes in various weights in grams. I have a one gram gold bullion and a 10 grams gold bullion in my entire collection. The one gram gold bullion was a birthday gift from mum when I was younger and still schooling. The 10 grams bullion was given by my rich uncle working as a doctor in Singapore, who love to play golf every weekend. Well, he is already a nonagenarian and is still in the pink of health as ever. He also goes to his clinic every day just to keep himself busy and active, but I am not sure if he has many patients as before or not.
