I believe they were only offered one year ( 2003 ) I paid $15.00 on the popular auction site however I believe they are probably worth more than that. I would guess in the $20.00 - $25.00 range ( however that is only a guess as I have only seen one for sale and I bought it.

" The S&W logo stainless steel 14 oz. mug is an uncommon item and was first offered in the S&W factory accessory catalog for 2003. Catalog number 150308 at $19.95 + S&H. It was not in the 2004 catalog, so I assume specimens did not fly off the shelf and it was discontinued. Ed."
