Gorham Coin Silver Pitcher. Help me find a year?

I’ve been doing a little research on this pitcher I just purchased but I’m having a hard time with the hallmark. I cannot decide what year it is. Is that a 3 in the center? and what would that represent? Was hoping someone here would have an idea. Thanks in advance.[/url]

Looks to me like the Gorham & Co mark for 1852 - 1865

I did see that just looking around online but just didn’t believe it so I wanted to get a second opinion. Thank you. Does the 3 mean anything or is it a pattern number or something? Thank you.
