ReceptionRating · Positive reviews · Number of ratings

Crown Currency Auctions holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Classical Numismatic Group has 107 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 20% of Classical Numismatic Group's written reviews are positive against 0% of Crown Currency Auctions's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Classical Numismatic Group ships an update every 5 months, Crown Currency Auctions every 15 months. The most recent releases landed on October 21, 2026 and October 17, 2026 respectively.
