Be aware most coins carry a premium because of the design / rareity. So you will pay for the gold plus some.
It can be fun to collect metals plus they have value. I once owned a 200g bar of silver. You can even get 1 and .5 g “cards” of gold for a lower end price.
Before jumping into this though I would warn you. The community around this can get a bit crazy. Many of them collect physical metals because they believe the economy will crash preppers style and we will need to return to metals as currency. It can ruin the fun of look at my stack of metals vs look how much gold I own on my screen.
