Bare with me I am new to this coin stuff. I went through all my coins and found a few coins that I have questions about.
I have a 1909 with what looks like a crack on the wheat side.
1928 with letters missing on the wheat side.
(3) 1957 "D" with the b in liberty filled on the bottom
The 1928 is just wear in my opinion. The 1957-D has a grease-filled die that does not give any special value.
"Money is like a sixth sense - and you can't make use of the other five without it." - William Somerset Maugham
"Never spend your money before you have earned it. " - Thomas Jefferson
The 1909 is definitely a cracked die, the 1928 is also most certainly a grease-filled die and the 1957-D is a die chip (yes, called the "filled B" variety)
