The Collateral Hellenic Territory is an administrative unit with no defined territory, located in the Hellenic Republic. It encompasses 1 hectare of land, with an undefined location. Its legal base is a Retroactive Unilateral Agreement with the Hellenic Republic, triggered by the Default of the Hellenic Republic on 2012-03-09 on bonds owned by institutions and citizens of the Federated Micronations.

The Federated Micronations administer the CHT via the Provisional Authority of the Collateral Hellenic Territories (PACHT).

Postal Services for the CHT are provided by Capricornia Post. Formally served by Capricornia Post until 2015-05-29, an agency office of the new CP subsidiary Capricornia Post Extraterritorial Agencies (CPEA) was set up on 2015-05-30, issuing stamps denominated in Euro.

The following stamps have been issued:

1) Commemorative stamp for the start of the postal service within the territory

Stamp - Start of the postal service

2) Series of 5 definitive stamps, depicting birds from the region

Definitives - lower values 0.10, 0.50, 0.70 Euro

Definitives - higher values 1.00, 2.50 Euro

On 2015-07-01, the Hellenic Republic defaulted on their debts for the second time in this century. This may lead to the cease of usage of the Euro currency in the Hellenic Republic. In this case PACHT may decide on the currency to be used in the Collateral Hellenic Territories. CPEA will issue new stamps or overprint existing ones to match this decision.

The debt conflict between the European Union and the Hellenic Republic is already causing much human suffering in the Hellenic Republic. PACHT and CPEA have agreed to donate 100% of all proceedings of the philatelistic sale of the commemorative and definitive series of CHT stamps. The stamps are sold at face value, plus EUR 2.00 for handling and shipping. A proof of donation will be provided, to a recognized society supplying aid to Greek citizens in need.
