As you know Thursdays guess was the milled edge of a coin, that was all I was looking for a COIN. The particular one was the edge of a £2.00(two pound) coin English currency. It was also a commemorative coin, commemorating the life of Isambard Kingdom Brunel(1806-1859) a great engineer of his time. For those interested a little bit about him can be found here. http://www.bbc.co.uk/history/historic_figures/brunel_kingdom_isambard.shtml Todays item again is in general use throughout the world in one form or another, this is synthetic but you can get natural as well. I said yesterday that todays would be harder or softer as the case may be. There is a clue in that. Again I urge you to think in macro, as you know it can be deceiving. PJ pointed out that it is difficult to photograph holes and this is full of them. Good luck. Thanks for stopping by for a look and for any comments you care to make. May the sun shine down on you where ever you are.
