Conservation Showcase: El Salvador 1992 2500 Colones
Posted on 5/3/2011
A recent example from our conservation laboratory.
Fingerprints are the bane of many numismatists’ collecting interests. Every new collector learns at length the proper way to hold a raw coin along the edge so as to not leave fingerprints on the surface of our numismatic treasures. Fingerprints do happen whether the result of handling by novice numismatists or as a tool of commerce long before the piece was valuable as an object of history. Fingerprints can damage the surfaces underneath and often do when found on classic coins.
This 1992 gold 2500 Colones issued by El Salvador was recently submitted to NCS to take care of the errant fingerprint across the reverse prior to having the coin certified by NGC. The coin was originally issued to commemorate the signing of peace accords ending a long civil war in the Central American nation. The fingerprint was able to be removed safely without damage to the surfaces underneath. This coin was able to grade very well with NGC following the conservation.
