Nice Country, How much You Want For It?

In 1868 the USA offered Denmark $5.5 million for Greenland and was told it wasn't for sale and they came back again in 1946 and slapped a cheque for £100 million on the table and were buffed again and when Donald Trump mentioned it in 2019 he was told in no uncertain terms to keep his teeny tiny hands off it but they are expecting him to come back again with another offer during his second term and the Washington Post did a calculation based on what America had paid for land previously and came up with a bill of $1.1 trillion.
Land has been bought and sold by nations for centuries, the Unites States paid France £15m for Louisiana and the Russian Treasury was bolstered by £7.2m dropping into their bank account when the USA bought Alaska off them and Mexico could buy a lot of Taco's with the £10m the USA paid them for present-day southern Arizona and southwestern New Mexico.
Denmark may have no plans to sell Greenland to America but they took £25m from them for the Virgin Islands which was more expensive than the £16m the USA paid Spain for the Philippines.
Hudson’s Bay Company sold Rupert’s Land to Britain for £300,000 and planned to sell it on for a profit to the USA but decided to give it away to Canada instead but England was not so charitable to France, making them cough up £5.3m for Dunkirk just after they had paid £3.3m to Sweden for St Barts.
Germany bought the Caroline, Palau, and Mariana Islands from Spain for £6.7m and the cost to Pakistan by bits of Muscat and Oman  was £1m while the Soviet Union emptied all their piggy banks to pay the £97.7m for Finlands Jäniskoski-Niskakoski territory.
The last land sale i could find was Belgium selling 2.5acres of land to the Netherlands for £30,000 in October 2024 due to the course of a river changing which left the tiny parcel of Belgium in the Netherlands.
