Coins are various metal currencies such as gold, silver, copper, etc., which are made by machines rather than by hand, and have a certain collector's value. Individually, they not only represent the monetary culture and technological development of each country in a specific historical period, but also the coins (machine-made coins) of different periods of each country reflect the social, economic and cultural backgrounds of different historical periods, and are important physical materials for the study of history. Collectible coins (vintage coins) were designed and made in a way that reflected the art of the time, and some vintage coins were made rare due to their small circulation and the difficulty of preserving them over time, thus increasing their collectible value. Therefore, not all coins are collectible, only rare varieties are collectible.
