Standing Liberty Quarter Errors

No, as for the dateless feature I was trying to clarify the level of wear on the coins. Thanks for the help on the supposed "die crack", I sometimes forget exactly what defines the error types. It is probably post mint damage. But what would be the value for a Standing Liberty quarter (probably about G-4 grade wise) with fairly prominent a lamination error on the reverse?

Have you checked carefully for a date? If you try different lighting you may be able to detect a date. Remember that error or not some of those are worth many thousands of dollars even as G-4. One of the big problems with error coins is the lack of a date and Mint mark. For example an offset coin without a date is only worth a dollar or so. The same amount of offset and the same coin with a date starts going well up there in value. Error collectors are a little fussy about that date thing. If you want a sort of decent explanation of the different types of error coins and their possible value look into a Red Book, 2009 edition, pages 401 to 404. Not complete but fairly decent.
