These are some unusual coins. Made in a handful of different denominations, these triangle-shaped oddities were minted in silver and gold to commemorate the Bermuda Triangle. The obverse shows a crowned Queen Elizabeth and the reverse displays a capsizing ship, compass, and map of the island.
All of these coins have low mintages (the highest was the $3 denomination with 5,000 made) and were struck with a proof finish. On top of the base values for the silver and gold content (up-to-date base values can be calculated by multiplying the 'actual weight' shown below by the current spot prices seen on kitco.com), these coins have a premium because of their unique shape and low mintage. Here are the catalog values for each version:
$3 coin -- 20 grams of .925 sterling silver, actual silver weight of .59 ounces -- $60 (U.S. dollars)
$9 coin -- 155.5 grams of .999 fine silver, actual silver weight of 5 ounces -- $200
$30 coin -- 15.5 grams of .999 fine gold, actual gold weight of .5 ounce -- $900
$60 coin -- 31.48 grams of .999 fine gold, actual gold weight of 1 ounce -- $1800
$180 coin -- 155.5 grams of .999 fine gold, actual gold weight of 5 ounces (wow!) -- $8,750
