I would suggest using Anthracite rather than Bituminous Coal. If you get high quality coal that is washed and sold for use in household fireplaces it should not be that dusty.  If you then brush any dust of each piece before putting it in your display then it shouldn't generate any fresh dust as long as it is not abraded. 
 
Anthracite has less volatiles and is harder to ignite.  Anthracite is the preferred coal for burning in domestic fireplaces as it is cleaner and produces more heat per weight.
 
Coal is harder to ignite than paper and many textiles.
 
NB charcoal is different altogether being processed (heated in the abscence of oxygen) wood. Charcoal is much more likely to generate dust.

Subject: Charcoal types for historic house museums

Hello All,
 
I work at an 1891 historic house farmstead with original coal burning fireplaces and stove. However, we are not a living history museum and do not use the fireplaces or stove for demonstrations. Some staff members want to have bituminous charcoal samples in the fireplaces and coal buckets to show children what would have been appropriate. I am hesitant to have actual coal in the historic house instead of reproduction for fear of combustion, off-gassing, and dust particles harming the collection. I have found that lignite is extremely volatile, but have not found the likelihood of combustion on bituminous. I would like to have some facts or statics to show our director on why we should not, or if it is okay, should use actual coal. Any thoughts or comments from those who have dealt with a similar situation would be most appreciated.
 
Thank you,
Hillary Kidd
