Here is a extremely rare CD 145 style Brookfield Salesman's Sample. Some say there are only 3 known.

It weights in at 0.7 oz and is 1 1/4" tall. The price range is $1,750 - $2,000. Normalizing that to 1oz, the price range becomes about $2,500 - $2,850. Today, the price of gold is about $1,050.

So, divide the price of the insulator by that and you get a number around 2.5 !! So, the insulator is worth 2.5 times its weight in gold. WOW!!!
