With the mintmark Mo, not Mxo, and the assayer "J", I'll venture a guess of either 1714 or 1717 since the date appears to be 171(X).
Great looking coin !! About 6.77 grams and .917 fine.

I'm thinking 1714. It may be a match to Florida Collection 11.00594. All these coins feature a crown that is higher on the left side than right from the shield, and a 7 in the date that is very long. The II for the amount usually touches the circular rim of the interior design.
