NSW 1813 DUMP, very rare.. it has great detail

 

However it has dark toned and porous surfaces, dealer says must have been buried hence the price drop.

 

What can NCS do about a coin that has had surface degradation like this ? obviously it can't be slabbed in anything except Details or Genuine holder.. which would be fine. Mainly thinking what can be done for eye appeal and to prevent any further corrosion occurring

 

Anyway, here's the coin, I know its just an image so hard to say etc etc :)

Unfortunately, porous surfaces are something that can not be helped through professional conservation. Corrosion has severely altered and damaged the surfaces and restoring those surfaces is something conservation would not be able to do.

 

Likely the best we would be able to do with a coin such as yours is authenticate it, then encapsulate it with a details grade.

 

I believe this is the question and response to your question about the crown coin:
