Hi, I just contacted the Gibraltar Governement (Treasury Department) to ask about the mint who produced the UEFA EURO2020 coins.
Their answer was: Dear Mietek,
The 20p collection was minted by AQ Pins & Gifts Co. LTD.
The £1 Gold Ingots were minted by Geiger Edelmetalle GmbH.
For the series of heptagonal 20 Pence coins, we need to create new mint (located in China): AQ Pins & Gifts Co. LTD - I was not able to find it on the list of existing mints (any mint from the city Dongguan)… Their website: https://www.aqpins-gifts.com/aboutus.html
For Geiger Edelmetalle GmbH - I just found on the Numista mint list their sister comapny Leipziger Edelmetallverarbeitung GmbH, Germany - and it looks that this is the right mint to be used for the gold bars with 1 Pound value as their mintmark <LEV> appears on these gold coins.
Not sure if this is possible but maybe you can add some information about their sister company “Geiger Edelmetalle GmbH” in the mint description (because it seems that LEV operates frequently via the Geiger Edelmetalle, like in the case of Gibraltar coins). More info here: https://www.geiger-edelmetalle.de/en/Company/
So please add AQ Pins & Gifts and if possible, add some info about Geiger Edelmetalle GmbH to the LEV mint page.
