Hi Nadine and thanks for joining us. Your mug probably dates from pre-1870 when Tiffany used the “550 Broadway” mark and the “Eng” for “English Sterling” prior to the term “Sterling Silver” coming into common use. The “925/1000” denotes the purity, or 92.5% silver which is “sterling silver”. The other numbers are the pattern and order numbers. You can research these in Charles and Mary Grace Carpenter’s excellent treatise, “Tiffany Silver”. A close up, clear photo of the marks will allow us to pinpoint the date further as the shape and placement of the components of the marks are important.
