Fire Damaged Coins

Without seeing pictures to asses the damage there isn't much I can say. Someone should come along that has had some experience in this area

Your question is to vague. You would have to actually see the type of damage that was done to the coins. For example if the coins were in any type of plastic holders or albums, the damage may only be plastic melted onto the coins. If the coins were in paper rolls, envelopes or cardboard they may just be darkened from smoke. On the other hand if the heat was intent and some coins were of the Zinc Cents, they would have melted onto other coins and that is fairly well the end. So much depends on just what was done. My suggestion is to ask if you can see them. If they are all melted together, to late. You would really have to see them yourself to ascertain the amount of damage. If those coins were in a metal safe with a nice fire rating, that is one of the mistakes people make. This does not stop the heat, only prolongs the ability to get inside faster. If those coins were in a safe, the heat still builds up if the fire is intense and the heat then stays inside longer once the fire is out. Also, if coins are in Albums such as Whitman or Dansco or others the platic slides melt right onto the coins and that is the same with slabbed coins.
Again, I would suggest you ask if you can see those coins.

I don't know about coins, but if they have any banknotes that are burnt you should contact the mint and see if they have a free service available to the public (or know about one).
In Canada, if any banknotes are burnt in a fire you can actually send the burnt notes to a branch within the Bank of Canada and they have a dept specifically for going through and calculating the actual loss. It will only be for face value of the note but it is free and something is better than nothing.
