An intriguing teardrop-shaped 4 Reales piece. The obverse displays a mintmark and assayers initial to the left of the Habsburg shield, which retains generous detail on its surviving sections. Below the initial is a bold crowned "F" countermark, intended to revalue the piece at 3 3/4 Reales.

An appealing example of this <strong>SCARCE </strong>issue.<strong>To view all items from the Pat Johnson Collection, click <a href="https://auctions.stacksbowers.com/lots?sort=auction_date_lot_number_asc&search=From+the+Pat+Johnson&limit=96&parent_category=1-11EIV&lots_range=upcoming"> here.</a></strong>From the Pat Johnson Collection.<p>Privately purchased from Mike Dunigan.
