I think you should buy your dad a camera and hide your coins

Nothing wrong with taking a rubbing. It's how coins were imaged long before photography was invented. If done properly, it won't hurt the coin.

It will bring out detail that might not show up on the raw coin. still not recommended.

I've tried it with my Austrian 1861-A 4 kreuzer - the place where the raw coin very distinctly showed "4 1861 A" was completely featureless on the rubbing. That, and I'd never do it with a high-grade coin (high grade here meaning anything above XF-40). *sorry for the edit, my experiment happened months ago and apparently I misremembered what the coin actually said*

Should really have more info on this one. There are what is called Graphite sticks. Even some pencils are all Graphite. Many artist too have Graphite sticks that are rather hard so rubbing anything like those over a coin, regardless of under paper, would leave marks on the coins. There are numerous ratings on Graphite items. And example is with penciles of graphite, they come with a numbering system from very soft to extreamely hard. So my question is what kind of Graphite item was he using?

Big Fred, thats exactly what my dad said!
Just carl, it was in fact a .07 or whatever graphite stick from a mechanical pencil. And it didnt do any good. the face of the coin kinda looks polished now

Do you mean it was a 7mm mechanical pencil? Here is a partial scale for graphite hardness. The "H" designates a level of hardness and "B" designates how dark/black the pencil would be.... 2H is harder than H. "F" means the pencil sharpens to a fine point. Most mechanical pencils in the US are HB I believe.
