What is these marks meaning~~~

thank you

From the crowned leopard’s head we know that this is a London hallmark. The lion passant mark is the English standard mark for sterling silver. The date letter t is the date code for the assay year1794/95. The king’s head mark shows that the duty (tax) was paid and the mark in the centre (which is upside down in relation to the other marks) is the maker’s mark HC for Henry Chawner.
