Obverse: Habsburg shield with Castile and Leon in correct order.  Mint mark "C" to the left of the shield, assayer "E" beneath mint mark.   Reverse: Cross with castles and lions, in correct order. Unlisted in R/L, L/R and C&T.  Dr. Restrepo has assigned the catalog number M36-5 to this piece.  Ex: Ponterio & Associates Auction 117, lot 1470, January 18 & 19, 2002.

Anverso:  Reverso: 

The coin presented here, Macuquina 1851, is unlisted in Calicó, R/L and L/R.  All three of these works record and illustrate a similar coin, with the denomination IIII to the left of the shield and the mint mark / assayer combination CE to the right of the shield.   Calicó (number 617c), R/L (M36-4) and L/R (M36C-4) illustrate the same coin.  Christensen  illustrates a Cartagena 4R with the denomination IIII to the right of the shield, but the mint mark and assayer are not visible and neither the obverse or reverse are the same as macuquina 1851.  Reference "Treasures of the Conception, May 14, 1982 by Henry Christensen, Inc." auction, lot 215.

If we compare 1851 with the Restrepo image we find the following diagnostics on the reverse (cross side).

1. Location of "H I" of HISPANIARVM.

2. Castles from same punch, notice the tall windows in particular.

3. Left cross arm has repaired break just left of the center of the cross.

4. Lions are made from same punch.

5. Top right lion has a stray mark extended down form the left foot almost to the cross arm, see photos below.

6. At 12 o'clock there is a cross at the top serving as a legend stop.  There is an unidentified mark extending from the arc to the left side of the small cross stop.  This mark comes after the final digit of the date.  Date not visible on # 1851.
