Nothing because while it is a commemorative medal it does not seem to commemorate anything.
These medals are on eBay at the moment for peanuts, so they're not worth much I'd say unless it's an official or endorsed medal.
what is the 1981 royal wedding commemorative crown worth
I believe it is worth 150,000.
Face Value
$6.00
An original medal is worth between £25-£30
the medal is worth about $100.00 but im not sure about the case
its worth about 500.00 in average condition
the Queen's Police Medal is priceless.
100.00 dollars
500 USD
Depends on which medal it is and what condition the medal is in. Just be more descriptive.
