The 1988 Macau Year of the Dragon Gold coin. Issued in 1000 Patacas. The Dragon is the most popular of collector items in Chinese culture.
As investments they are always likely to hold their value over time.
The coin is part of the Macau series I collectors set. As with many of the Macau gold coins in these sets, their mint estimates are unlikely to be near total due to the coins being handled and melted over the years.
