According to Walter Breen, six pairs of dies were available for striking 1844-O Eagles.
Despite a relatively high mintage of 118,700 coins, the 1844-O Eagle is a scarce date. The grade seen most frequently is XF40. AU examples are very rare and only a few of pieces are known in Mint State. A single Proof example is known of this date.
In August, 2004, NGC published a partial population report of gold coins recovered from the shipwrecked SS Republic. Included were 32 1844-O Eagles, ranging in grade from AU-50 to MS-62. 20 of the coins were listed as "Doubled O".
