  There is also plenty of documentation and books to learn coding and start auditing if you want to. Fake validation is less like coding as to catch a really well made fake you would need years of experience seeing all sorts of fakes , while coding needs only experience to see what is good code to able to catch most issues

      Less bugs would be there if the industry wanted it and paid for it. Sadly the problem is good enough is how the industry sees everything, constant cost cutting , off shoring or replacing senior talent with fresh graduates , inadequate focus on security, debt is all too common, unless/until something affects bottomline there is no pressure.

But this page covers everything from $1 to $100 (although it seems the $1 and $2 have barely any.) https://www.uscurrency.gov/denominations/ https://www.uscurrency.gov/denominations/
