Silver and gold examples, if original, are usually an order of magnitude more expensive. What does that mean?
cost more of course! Gold pieces just aren’t that common and therefore are usually quite expensive. This is true of silver pieces as well with a major exception springing to mind; Napoleon’s coronation. Here, silver pieces were struck in large numbers and obviously saved by the recipients considering how common they are. The really common silver are the 15mm coronation pieces that were produced to be thrown to the crowd. I have purchased these as low as $15 and have seen poor examples sold for as much as $50. They’re probably worth $25-30.
