The sale of 20 stamp albums has raised £1,000 for the RNLI lifeboat station in Hartlepool.
The albums were donated anonymously to be auctioned in aid of the station.
They were sold by North East stamp dealers Corbitts at an auction attended by about 200 philatelists.
Chris Hornsey, lifeboat operations manager, said the "extremely generous donation" would help provide "first class kit" for crew members.
He said funds would also help maintain two lifeboats at the Ferry Road lifeboat station.
