Greetings and welcome.

Most coin collectors have their "trigger moments", a specific moment or event in their life that sparked their passion and activated the coin collector genes which they almost certainly didn't inherit from their parents.
For some, it was when their beloved grandparent/parent/aunt/uncle/mentor/father-figure-etc gave them an old coin.
For some, it's finding an old, decades-obsolete coin in change, or hiding lost in an old piece of inh
erited furniture.
For some, it's finding a foreign coin in change, or going on a foreign holiday themselves and encountering foreign money for the first time.
For me, it was going to a "coin and stamp show" as a kid with my parents, and seeing really old foreign coins - coins that were "older than Australia" - for the first time.
For you, it was going into a mint gift shop and seeing bullion coins for sale.
It's all good.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
