Do you know the heaviest and lightest coin ever made?
The heaviest coin ever made was the Swedish 10 Thaler, weighing over 20 kg.
Now he can buy two cows. The smallest coin in history was Jawa, Nepal, weighing just 0.014 g.
Can you believe that even this small coin was shredded into smaller pieces for use as change?
With this currency, you need very good eyesight to get accurate change!

How Do Dogs See Color?
Unlike humans, who have three color-sensing cone cells in their retina (red, green, and blue), dogs only have two of them (yellow and blue).
It's not that dogs can't see green or red objects.
It simply means that they cannot distinguish green, yellow, or red objects by color.
