5 euros Verseau or

Part of Monnaie de Paris's ongoing zodiac series, this miniature gold piece corresponds to Aquarius — the sign covering roughly January 20 to February 18. At half a gram of .999 fine gold, these fractional issues are produced primarily for the gift and collector market, a format Monnaie de Paris has leaned into aggressively since the early 2010s as bullion demand for sub-gram denominations grew across Europe. The 5-euro face value is nominal; no one is spending it.
