Great Britain
Selections from the Eric P. Newman Collection of World Coins. William & Mary tin Halfpenny 1692, with official copper plug at center, S-3449, XF45 NGC. Little actual wear but struck from heavily rusted and corroded dies, therefore lacking detail. The flan itself is mostly sound, showing on a small amount of black oxidation. The date is all but unreadable.
Estimate: 600-800 USD
