The Republic of New Granada consisted primarily of present-day Colombia and Panama with smaller portions of today's Ecuador, and Venezuela. It was created after the dissolution in 1830 of Gran Colombia, which encompassed much of northern South America and part of southern Central America starting in 1819.
This is an example of a coin that is quite common in worn condition, but very rare in well preserved condition. The catalog does not list values for coins with less wear than well preserved (XF) condition. There are just not enough uncirculated coins available to establish value.
The coin in our picture is a rare exception. It was sold by Heritage World Coin Auctions in New York for $2200 US dollars during a 2014 auction. CoinQuest thanks Heritage World Coin Auctions for use of their coin photo. It's really cool!
Here is what the catalog says for worn and average circulated coins:
worn: $50 US dollars approximate catalog value
average circulated: $125
well preserved: $285
fully uncirculated: $800 and up
