On fire
... or know what it is?

The first known crest (1946-1975) to be used by Brighton & Hove Albion was the traditional coat-of-arms design of the twin towns of Brighton and Hove. A hybrid design employing the shield of Hove and the dolphin crest of Brighton was also used at times while a calligraphic shield was worn on the team shirts in the latter 1950s. During the 1974/75 season the club became known as 'The Dolphins' and by the beginning of the following season, a new club crest had been introduced. Both this nickname and crest were to prove short-lived, however, following an incident said to have taken place in the Bo'sun public house in Brighton. Prior to a 'derby' fixture with fierce rivals, Crystal Palace, a few away supporters started chanting, "Eagles, Eagles" to which a group of Brighton & Hove Albion fans responded with a chant of "Seagulls, Seagulls". Current club director, Derek Chapman, is said to have been among the group who first christened the club with this nickname. The club has been known as 'The Seagulls' ever since and in 1977 the club crest was changed once again to represent this.
That's the coat of arms of Brighton. The Latin is "In God We Trust".I have something similar. A plaque on my wall in my lounge, presented to me by Brighton Council as a Yacht race prize.
However mine says" In Deo Fidimus," and not what is on that one. I don't speak Latin and Jnr isn't here at the moment, so unless LB does we might not ever know what it is.
