Number plates making clear which side of the Brexit divide drivers are on have been selling for up to £1,500.
Plates sold so far include EU20 BYE, EU20 LUV, and EU20 BRX.
The UK is currently scheduled to leave the European Union at the end of January, pending the result of December’s general election.
Plates with the ’20 year marker are now available to buy, though can’t be put on cars until March.
Personalised plates see car owners pay extra to have a letters spelling out a recognisable phrase, slogan, or abbreviation on their numbers plates.
James Russell, a spokesman for National Numbers, a private dealer of the plates, told Metro that his company had received numerous calls for people hoping to secure a Brexit-themed plate.
“Normally with private plates they often don’t spell out the word perfectly, but these are to the point,” he said.
“When people have a bit of extra money to spare they like to share their thoughts, especially on Brexit.
“We have had a lot of enquiries.”
He said people phoning had been from both sides of the debate over whether Britain should leave the EU, though most were opposed to the idea.
He said that around 20 plates directly references the issue had sold for prices between £500 and £1,500.
Asked which he liked best, he said: “EU20 FAN is my personal favourite.”
In the UK, personalised plates are issued by the Driver and Vehicle Licensing Agency, the government organisation responsible for maintaining a database of drivers in the country.
