Type I, an SS Central America "show off" coin. Type II This type is hard to find in Choice or Gem Mint State because there have been no major sea salvage discoveries. $20 was too much for collectors to set aside for a collection back in the day. This one is graded MS-63. Any higher than that is hard to find and expensive. AUs are fairly easy to find. Type III I like this one because of the date. The presidential election was the big contest between gold vs. silver. This one is also graded MS-63. Time was it was hard and expensive to find these in MS-65, but lower grading standards have increased the population. A "silver bug" button.
