Solid gold sacra or cartagloria— the plaque on which are inscribed the Words of Consecration— mounted on hardwood, part of the extensive liturgical treasury of San Agustin church in Manila.
"… but the most precious liturgical item which has survived all these turmoils is a sacra, a plaque with the words of the Consecration, of pure gold mounted on wood. Possibly a 17th-century piece, it formed a part of the treasure evacuated to Pampanga in 1762, just before Colonel Draper’s men looted San Agustin. This sacra was brought out only for the feast of San Agustin, and immediately brought back to the vault after the ceremony. It is an excellent and exceedingly rare example of the gold which left Manila aboard Acapulco-bound galleons."
