Green is not a good color to get if you are testing sterling or pure silver. That would indicate a higher copper content. Stuff just marked MEXICO comes to mind. Get an acid test kit and use the one marked 18K to test sterling. Good stuff will turn a milky white.
The most money I made are on coins I haven't sold.
