The 1925 Lex-Concord Comm. Half Dollar: the original holders were made from uncured Pine wood boxes! Some Brilliant coins are as green as a breath mint...   Edited by Oldgrouchyguy

Residue is residue no matter what the source - it didn't leave the Mint with residue on it. Just another CON checkmark in the "Use a TPG" spreadsheet. |

DOCC: of course, but this type of residue is a natural product of the Official Holder-of-Issue; other holders have coins tone in them, this issue gets pine-sapped

I seen one of those that was still in the original box sold off on ebay years ago. The coin showed showed the effects of having been stored in it for a long time. |

A 1925 Lexington-Concord Sesquicentennial Half Dollar that was stored in an original wooden box for a long period, and thus showing a change in surface color, is considered to be toned, not covered in residue. As such, it is readily graded by the major services.

Yes, and this is the only classic coin of all straight-gradable coins that could be graded, coated a naturally-occurring foreign substance, that is not struck-through at the time of minting. No one is arguing what is Toning, just that this particular toning is from pine sap Edited by Oldgrouchyguy

But this has the appearance of a sticky residue (sap), not toning that most associate with the natural progression of silver oxidation. My overarching complaint with TPGs is the complete lack of consistency. This straight grade is just another anecdote - shame on ANACS in my opinion. Beautiful coin nonetheless, thanks for sharing. |
