Stamps can be categorized into three main types based on their rarity and collectible value. First, extremely rare stamps, which include historical stamps, limited editions, or those with printing errors (error prints), making them highly sought after by collectors. Second, rare vintage stamps, which are antique and unique stamps from a specific era with high artistic and historical value. Third, common stamps, which may initially seem ordinary but can suddenly become rare and valuable if they go viral on social media, attracting collectors and market interest.
