The plaque commonly displayed the name of the ship, as well as its class and shipyard of origin. Many later plaques also displayed the ship's official motto, plus a list of notable Starfleet officers involved in the assembly of the vessel.
After earlier being made to wait for quite some time by the Sheliak, Captain Picard took his time answering their hail, inspecting the ship's dedication plaque in 2366. (TNG: "The Ensigns of Command")
When USS Voyager found the USS Equinox in 2376, Captain Janeway noted that the Equinox's plaque had fallen, and advised that they should hang it back up. Similarly, after days of battling with the Equinox after they betrayed the Voyager crew, Voyager's dedication plaque fell down. Janeway noted that, after years of battles, it had never fallen down before, and in a symbolic gesture, they put it back "where it belonged." (VOY: "Equinox", "Equinox, Part II")

Background information Edit
According to the Star Trek Encyclopedia(citation needed • edit), the dedication plaque on the Galaxy-class USS Odyssey, seen in the Star Trek: Deep Space Nine episode "The Jem'Hadar", had the following quote: "Its origin and purpose, still a total mystery." The quote is inspired by Dr. Floyd from Arthur C. Clarke's 2001: A Space Odyssey:
"Dr. Floyd: [prerecorded message speaking through TV on board Discovery while Bowman looks on] Good day, gentlemen. This is a prerecorded briefing made prior to your departure and which for security reasons of the highest importance has been known on board during the mission only by your H-A-L 9000 computer. Now that you are in Jupiter's space and the entire crew is revived it can be told to you. Eighteen months ago the first evidence of intelligent life off the Earth was discovered. It was buried forty feet below the lunar surface near the crater Tycho. Except for a single very powerful radio emission aimed at Jupiter, the four-million year old black monolith has remained completely inert. Its origin and purpose are still a total mystery."The dedication plaque however, was not visible on screen in the final cut of the episode.
In the non-canon Star Trek: Titan premier novel, Captain Riker has a tough time selecting a proper quote for the USS Titan's dedication plaque. It has never been implied, one way or the other, if it is standard procedure for a ship's captain to choose the quote on their own ship's plaque.
