Wow what an amazing collection!
You do have such a wonderful way to share the history of Brazil through these coins- so many layers of stories with each coin through each period.
And you're so right, anyone that comes from a country with a stable-ish economy and singular relationship to the motherland- like us Aussies who have only ever had the hand-me-down currency of the UK, until decimal currency became the norm, it is hard to imagine such a century with so many iterations due to so many political upheavals.
And your collection, dating back as far as the late 1800's puts mine to shame, though I did state that old coins for us here in Australia, would be considered pretty recent for the rest of the world- as with all of our European based history..so it's totally weird that we are talking about the same thing but through 2 completely different lenses.
But wow, what am awesome collection you have there and I really hope that you can keep it in your family and have it kept safe, handing it down to each emerging generation.
