To put it bluntly I'd be suspicious as to whether that is really anthracite. The going rate at the breaker is in the neighborhood of $130 and it certainly cost more than $40 a ton to get it to Colorado from here in Pennsylvania. Anthracite is only available in Northeastern Pennsylvania. The cost for example in Maine and other areas where its about 8 to 10 hour trip one way is about $300+/- a ton retail.
I want to encourage the use of anthracite but I don't want to see people spending their money unwisely either and if you expect to burn anthracite you better make sure that's what you are getting and will have a reliable source for it for many years if you invest in a boiler or even an anthracite stove. With the demand rising like it is the chances of having a reliable source that far away is pretty slim. You can't burn bituminous in a unit designed for anthracite. Bituminous is very abundant in your area, if you want to burn coal that is probably your best route but you also have to understand the issues with that, first and foremost is that it produces a lot of soot and smoke when burned.
EFM is working on design for a bituminous coal boiler, you may want to check this thread.
