coindexter Pillar of the Community United States 869 Posts	Posted 11/23/2008 4:54 pm I think kurtS gave me some good luck the other day. I had these 3 pop up in my last roll search. I like the dime die crack the best. The 98-P cent on the left had 4 cracks, 1 on obverse and 3 on reverse. That die must have been ready to go.Here are closer up pics of it. The obverse crack is kinda weak. Edited by coindexter 11/23/2008 5:33 pm Report this Post to the Staff

coindexter Pillar of the Community United States 869 Posts	Posted 11/23/2008 11:14 pm Are they common when one coin has 4 on it? It's my first one I have seen. Well I'm sure everyone has one. I just haven't seen any posted on here with 4 cracks on one coin recently Report this Post to the Staff

coindexter Pillar of the Community United States 869 Posts	Posted 11/24/2008 1:37 pm Nice Morgan It's all cracked up to me.Anyone know what metal the dies where made of back then? And now?.The dies must last longer today by using newer alloys or something. Someone here should be able to answer that one. Maybe biochemistI will eat my popcorn and wait.....

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 11/24/2008 3:42 pm There may be a slight difference in metallurgical content but it is not like they are using some revolutionary new alloy that wasn't available 100 years ago. Annealing techniques are probably more quality controlled today so the dies tend to have a more uniform strength from die to die. The main differences would be striking pressure, the size of the coin being minted, and the relief of the design. The bigger the coin, the higher the strike pressure required so that is hard on the dies. You also need high striking pressure for a coin with a high relief so it will fully strike up. Notice that many of today's designs seem flat and lifeless, the lowering of the relief allows for a lowering of the strike pressure thus extending the life of the dies. Report this Post to the Staff
