These dinner forks (and my other listed Francis 1st items) were purchased in the 1980s and have seen light use. Some require polishing as they have been in a flatware box for the past 30 years.
These salad forks are:
6 1/8 inches long (157mm)
41 grams in weight (1.32 troy ounces)
92.5% solid silver
I'll save you the trouble of calculating the silver value. On the date of posting, silver is $31.90 per troy ounce. So each fork contains $38.95 in silver.
Love them or return them for a full refund of the purchase price.
