Like Biokemist, I would need to know to what you are referring. If it's die cracks, die chips, and Grease Filled Dies, you're not going to find any reference at all on them. If you are looking for a price guide of off-center cents by date and mintmark - it isn't going to happen. There isn't one, and never will be one. Errors are simply not just "priced" like normal coins. Reason - a number of factors go into the value of any error:
1. Date and mintmark.
2. Grade of the coin.
3. Rarity of the error.
4. Whether the error could have easily escaped the mint through normal channels.
5. Popularity of the error type.
...and other factors my tired brain cannot think of right now.
I can guarantee you that you will forever have a hard time selling die cracks, Machine Doubling, die chips, "missing" letters coins, and other minor anomalies because ANYONE can find that stuff in their change. They are very highly unlikely to want to pay a premium for stuff like that because they aren't one in a million. They are more like five in a thousand. The errors that actually have value (and in my opinion are the ONLY ones worth collecting) are the coins that are a one in a million find in change...indents, brockages, large broadstruck pieces - the stuff you simply are not likely to "find". That's what makes them scarce, that's what makes them collectible. The coins people post here are generally just pocket change, and always will be - no premium value. You'll NEVER find stuff like that listed in any price guide. They have no premium value and never will.
