• It’s a pretty enormous amount of money now. I was thinking that a gold coin was 1oz which would have been an insane amount of money but some research has told me that guilder can refer to several different coins that are between .08oz and .11oz of gold mixed with other precious metals. Ignoring the other precious metals and assuming the lowest gold content 1457.5 guilders is a bit over 116 oz of gold. Gold is approx. $1900/oz so in gold alone that is over $220,000.
