One Troy Ounce
I had my scale out the other day and my son wanted to weigh some coins with it, and was surprised to see them weighing more than an ounce - I realized the scale had an "ozt" setting, nice.
There are 31.1035 grams in a Troy Ounce - much different from the regular 28.3498 grams in a common Ounce. The Troy Ounce is used for precious metals like gold and silver. It would make a big difference in calculating premiums, especially with gram denominated pieces.
JBR Logo 1oz Silver Round
Minted by JBR, their Logo stamped, British themed, one Troy ounce round is 999 pure silver. It's a part of their Icons of Britain series.
The front of the round features the "999" text in the center with "JBR" above it, and "RECOVERY LTD" just below it - the JBR Logo stamp.
Along the top curve of the round is the text "ONE TROY OUNCE", along the bottom curve of the round is "999 FINE SILVER".
The backside of the coin features many depictions of British life, culture, icons, and monuments - like the Red London Bus, the harp of Ireland, London Bridge, the Queen's Guard, a tea kettle, and many more.
The British Icon pics on the backside are a good look. A fine pair of One Troy Ounce 999 silver rounds to clank together, a nice addition to the stack.
