IPA: /ˌʌnˈsɜːrkjʊleɪtɪd/
KK: /ʌnˈsɜrkjʊleɪtɪd/
Describing something, especially coins or currency, that has not been used or exchanged and is kept in its original condition.
The collector was excited to find a set of uncirculated coins from the 1800s.
Uncirculated → It is formed from "un-" (meaning not) and "circulate" (from Latin "circulare", meaning to move in a circle or to flow around). The word "uncirculated" means not having been circulated or distributed, particularly in the context of currency or coins that have not been used in transactions.
Think of 'not' ('un-') having 'flowed around' ('circulate') — that's why uncirculated refers to something that hasn't been distributed or used.
