Shipwreck effect grade scale

Hello 1861-O Liberty Seated Half Dollar NGC Shipwreck Effect grading? What is the difference between a coin W-04 and 4-06? Thanks for your help

Your coin was recovered from the SS Republic and was corroded by long immersion in seawater.  If it wasn't from a known shipwreck it would just be called details corroded, but they came up with the term "shipwreck effect" for marketing purposes.  A corroded coin commands a big discount, a "shipwreck effect" brings a premium.  The W-04 and W-06 refer to the die variety of the coin.  There are 15 die varieties of 1861-O half dollar.  The W-04 and W-06 were struck while the New Orleans Mint was in the hands of the State of Louisiana.

Thanks for the help is there a difference in price of a W-04 W-06 or any other of the 15 die varieties?

I'm not familiar with Liberty Seated coinage die varieties but as a general principle, only if there is someone out there who will pay a premium for it.  Self evident answer I know but most date/MM combinations were struck from more than one die but don't have a premium because no one wants it badly enough.  To my knowledge, there is minimal die variety collecting in Liberty Seated halves.

One of them, I think it's W-12 uses the same obverse die that was used to strike the 1861 Confederate half dollars, and it will bring a premium. A couple of the other later varieties which are easily recognizable and were used by the Confederacy will also bring a smaller premium.
