Your a better dad than me lol...as my kids were growing up I gifted them au and ag for gifting occasions.... probably 10 yrs ago my son sold me back most of his to put into the s&p500....my daughter has always had me hold hers for her ...... could never get either one to invest more.....my daughter may change her mind soon as her last trip to India she was exposed to a gold saving culture and commented on it...maybe they think dad has them covered lolI got my son to start buying 2 years ago. He was able to buy when Au was < $1900 and platinum < $950. He also picked up a little bit of silver < $30.
His favorites are pre-33 numis and 1/2 oz Canadian silver polar bears he got just.over spot in a special sale.
