The end of another busy day

Been stuck inside most of the day with no time to get out and get a blip so have had to resort to taking pictures of coins again today.
This is of an image on the back of a Guernsey 20p coin.
The outline is of the island inside a cog.
Amazing detail for such a small object the inside diameter of the circle is about 7mm according to my measurements.

Have a feeling that there is going to be some strange objects posted on my blip over the next few days as it looks like it is going to be a busy week.
