If I'm understanding your question correctly it's typically 1/20oz but you would be best to avoid buying such a small size bar because it would incur gross premiums. With gold you typically wouldn't want to buy anything smaller than 1/10oz due to premiums but most would say if you have the money go for 1oz at a time.
How many ounces is in the smallest bar?
You can buy gold and silver by the gram, you do t need to buy a full oz

EDIT: Not that I care but why the heck would my answer get downvoted.
He asked how many OUNCES are in the smallest bar.
Can someone prove that you can by smaller than a 1 (one) ounce bar?
Yes there are grams and so forth but read his question again......
I'll wait.
