Watch List notes:

MEXICO. Mint Error -- Full Obverse Brockage -- 4 Reales, ND (ca. 1863)-Go YF. Guanajuato Mint. PCGS Genuine--Tooled, VF Details.
cf. KM-375.4. This highly interesting and seldom encountered error displays a bold nearly complete incuse mirror image of the reverse. The surfaces display beautiful rich old cabinet patina with lovely iridescent hues that become apparent when rotating in the light. Close inspection reveals evidence of numerous light scratches around and amongst the devices from long ago, long since toned over and very attractive. Despite its shortcomings this wholesome looking error is pleasing to the eye with a fantastic appearance that is sure to excite many collectors.

The circa date for the present piece is based on specific die characteristics and diagnostics. Identification of minor die degradation can with a decent amount of certainty place a mint and date to this survivor. Most notably the crossed branches beneath the mound are broken and segmented with faint remnants of a horizontal line in the middle below. Several other features such as the shape of the eagle's tail, the thinness of the snake in the area between the eagle's beak and neck as well as the curvature of the eagles left most talon on the cactus with a single dot near the right most talon. Though unconfirmed, more in depth research and comparison is needed from a specialist to confirm these findings. To view all items from the Pat Johnson Collection, click here.
