I picked up this coin at the September 2013 Dallas Coin Club Auction, where the club sold a large collection of items bequested from the estate of a former member. I’m not very familiar with coins from Guernsey, but would grade this to be between Very Good & Fine.
The center of the obverse is dominated with the crest of Guernsey – a shield with 3 lions passant to the left. There are dots all around the inside rim. I tried counting them but lost count 5 or 6 times & gave it up as a lost cause. From 8:00 to 4:00 along the inside of the border is the legend “Guernsey”.
On the reverse, the 4 Doubles has the same border of dots, with the denomination in the center “4 Doubles” over the mintage date “1889”.
