This coin (well Token) is an AH1250 (1834) Keping from Trumon, which is a state in northwest Sumatra. After photographing it to post on my forum, I noticed what could be a couple of Die Cracks on the Reverse. Am I wrong?
A die crack is a raised metal line above an evenly flat surface. A planchet defect shows two uneven surfaces with one higher than the other. And that's what it looks like in the pics.
I put the question to Laz of World Coin Collecting forum, and after looking at the coin a little more closely, there are 3 more cracks in the coin, which lend me to think it was actually a shattered die. But who really knows?
Those are die cracks or at least the result of die cracks. The differing heights on either side of the crack is because part of the die is sinking so the field of the die is actually at two different levels. When a piece of the die sinks far enough that the details become weakened but still visible then we call it a retained cud. (The wedge shaped piece from 6:00 to 8:00 is sinking and begining to form the retained cud.) If the piece of the die falls away completely then it forms a full cud. Usually you get retained cuds and differing die levels like this if it is the anvil die that has cracked because the collar holds the pieces in place and does not permit them to fall away.
