... unless they mean Australian dollars in which case it is true.

The original article at earthtimes.org (archived) claims:

GLASGOW, Scotland, Nov. 28 Scotland has replaced its airport signs proclaiming the country to be "the best small country in the world" with a new slogan: "Welcome to Scotland." The new slogan, which was revealed Tuesday after six months of development and $250,000 spent on the project, is also printed on the posters in Gaelic as "Failte gu Alba," The Times of London reported Wednesday.

Confusingly it is tagged with US World News even though earthtimes.org is a British website.

According to articles from BBC and Daily Record from 2007, they spent £125,000 on the change. I could only find exchange rates from 2009, and 125,000 GBP would be 181,187 USD or 257,050 AUD.

Note that this only covers the signs at the airports:

A government spokesman said the £125,000 cost of the displays covered the new artwork, printing and installation.
