2012) 200th Anniversary of the Greek Revolution, Greece: A 2 Euro Coin issued by the Mint of Greece commemorating the milestone: Year of Coin issue: 2021:

The celebration of the Greek Revolution of 1821, Cyprus and Greek diaspora takes place on 25th March every year, coinciding with the Feast of the Annunciation.

The day is a public holiday in Greece and Cyprus.

 Usually celebrations include parades and other celebratory events on the same day or its eve. 

The largest event is the military parade in Athens on 25th March, while on the previous day, celebrations take place throughout the schools of the country. 

In other municipalities, parades of military divisions, students, clubs, etc. are held, as well as church services.

More broadly, the holiday acknowledges the successful Greek War of Independence (1821–1829) was fought to liberate and decolonize Greece from four centuries of Ottoman occupation. 

After nine years of war, Greece was finally recognized as an independent state under the London Protocol of February 1830. 

Further negotiations in 1832 led to the London Conference of 1832 and the Treaty of Constantinople (1832); these defined the final borders of the new state and recognized the king.

The holiday was established in 1838 with a Royal Decree by King Otto's government.

6) Polar Climate Zone: "Climates of Earth Coin Series": The fifth "tri-material" Coin in the series with an outer ring, inner core and an ebbossable violet polymer ring: An innovative coin issued by the Federal Republic of Germany in 2021

In 2021, the Federal Republic of Germany issued its fifth polymer 5 Euro Coin with the theme "Polar Climate Zone" with a green polymer ring.

This coin is the fifth in a five-part "Climate Zones of the Earth" Coin Series, with one coin being issued every year from 2017 to 2021. 

Like all the coins in this innovative Coin Series, this coin too is linked to the very first innovative 5 Euro Coin titled "Planet Earth" (which marked a global premier with its translucent, coloured polymer ring in 2016).

The five coin series includes:

2017 "Tropical Climate Zone" - Red Polymer Ring

2018 "Sub-tropical Climate Zone" - Orange "  "

2019 "Temperate Climate Zone" - Green   "  " "

2020 "Sub-polar Climate Zone" - Turquoise "  "

2021 "Polar Climate Zone" - Violet              "   "

As with the earlier coin, this 5 Euro Polymer Coin consists of three components - outer/external metallic ring, an inner metallic core and an embossable green ring.

The Reverse and Obverse of the Tri-material Coin  titled -"Polar Climate Zone".

The Violet ring is partially translucent and is permeable to light. The ring has been inserted between the metal components and forms a permanent bond. At the same time, the ring evokes the coin's motif "POLARE ZONE" (meaning "Polar Climate Zone") on the lower periphery in a striking way.

The Obverse of the 5 Euro coin represents the development of the cultural landscape, which defines the Polar climate zone, by depicting an ice shelf, an iceberg afloat in the water and a seal swimming.

The Reverse of the 5 Euro Coin shows the German Eagle emblem, the country name "BUNDESREPUBLIK DEUTSCHLAND" (in German) on the lower periphery, face value "5 EURO" on the upper periphery, the 12 stars of the European Union (EU), representing the countries which had initially joined the EU and the year of issue "2021" below the Eagle emblem.

The coin will be legal tender in the Federal republic of Germany.

The specifications of this coin are:

Year of issue: 2021; Coin Quality: Brilliant Uncirculated and Proof; Metal Composition: Copper, Nickel, Polymer; Diameter/Size: 27.25 mm; Weight: 9.00 grams; Minted by and Mint Mark: Berlin (A), Munich (D), Stuttgart (F), Karlsruhe (G), Hamburg (J). Each of the five German mints will strike a version of the Polymer ring with a different shade of violet; Edge Inscription: The smooth rim is embossed with the inscription "KLIMAZONEN DER ERDE" (in German) - translating to "Climate Zones of Earth"; Mintage: 300,000 pieces (Proof) and 2000,000 pieces (BU); Obverse designer: Peter Lasch; Reverse designer: Stefanie Radtke.
