Easily confused with William Hall’s “Grasshopper” lock, it is a Linus Yale Sr. lock known as the “Peanut” lock, in reference to the key itself. Quite rare but I am not the one to put a value on it. I agree the safe was not made by Yale Sr. and was likely a New York maker like Herring. However, contrary to the commonly held opinion in the trade of Yale not making safes, there is good evidence Linus Jr. was making money chests during the same time period the keylock was made.
