NCS November 2017 Highlights

Numismatic Conservation Services (NCS) uses a variety of proprietary techniques to remove harmful surface contaminants, stabilize and protect a coin's surfaces and, in may cases, improve a coin's eye appeal. After coins are conserved by NCS they are seamlessly transferred to Numismatic Guaranty Corporation (NGC), an independent affiliate of NCS, for grading and encapsulation.

Below are a few highlights of coins that were conserved by NCS and graded by NGC recently.

This Mexico 1999 1/20 Onza, or ounce, gold coin arrived at NCS with a severe red spotting problem. Spots such as these can occur on modern coins from around the world and can be particularly troublesome on such a diminutive coin such as this. Using specific conservation techniques, NCS has developed techniques to remove these red spots. Following careful conservation work, this gold coin was able to grade spot free with NGC.

[2814681-010] This Great Britain 1799 ½ Penny proof strike in gilt came to NCS in need of help to remove the thick layer of green and white residue obscuring the original surface in a spotty pattern. Many decades of improper storage likely allowed the residue to develop; a problem that frequently plagues many classic proof coins. Careful conservation work was able to remove the thick layers of residue leave a coin with brilliant surfaces to grade with NGC. Unfortunately due to the scratches present on the obverse from prior to conservation this coin graded with details.
