Restore Date On Standing Liberty Quarter?

I was wondering if anyone has tried the iodine method on dateless silver coins to try to restore them?

I would think the problem there would be that as it reacted it would form silver iodide which has the same problem as nitrate products, silver iodide turns black instantly upon exposure to light. That's why it was used for photographic plates back in the early days of photography.

In a few cases, yes, they can absolutely be worth more than melt. The most obvious examples would be one or two year type coins that are identifiable such as the 18th/early 19th century Flowing Hair and Draped Bust designs and even the 1916 SL quarter(a couple minor differences between a 1916 and 1917). However, most coins are virtually obliterated by the time they are dateless, SLQs and Buffalos being the main exceptions due to flaws in the date placement. For most issues, the date is protected from excessive wear in a reasonable manner.
