1. Commemorative memorial UK medallion for King George IV



Obverse: Laureate draped bust of George IV, left
Lettering: IN MEMORY OF GEORGE THE FOURTH

Reverse: Weeping willow bending over funerary urn on plinth
Lettering: BORN AUG 12 1762   CROWNED JULY 19 1821
 The urn is inscribed: OBIT JUNE 26 1830

Size: 25mm
Metal: Brass


 The willow tree and urn made me think of the medallion I have, but I now see mine is 1837
so is 7 years later, for William IV https://en.numista.com/catalogue/pieces57278.html

and 2,3 might be fakes?

2 and 3
 Look rather like on here in the section  Tokens - German States (Nürnberg)

For example, number 3 may be  https://en.numista.com/catalogue/pieces30265.html

Lovely the first one, is it valuable?
The 2 and 3 are really hard though, might be the one you gave

 The crowned orb of Nuremberg is called a Reichsapfel, which appears on the reverse. The obverse sometimes has crowns and fleur-de-lis, or ships, and so on.
