I'd keep those slabs and make something out out them, definatly keep those spalted Maple slabs for sure. Cherry wood is fairly common , figured or not it won't bring much. Whatever you make out those slabs will probaly be worth more than what you can sell them for. Unless you live near some mountains where people have log homes and lots of disposable income where eye catching wood will fit the decor of the home the market for slabs, rustic furniture, ect.,ect. is very, very limited . The percentage of the woodworking community who might have an interest in slabs is probaly well under 1% based on my same type scenario of trying to sell slabs and rustic benches using slab wood. I think I am speaking the truth is that most people weather they work with wood or not don;t know what a live edge slab actually is. . Most wood guys think in terms of planks and planed boards measured in inches, not by quarters of an inch.
It is hard to put a price on an item that has taken time, money and sweat to achieve a certain goal, in this case an eye catching slab. Most people have a mindset of what they are going to pay for an item. In this case a colorful, large ,thick piece of wood. It doesn't mater what the dimensions are, nor the grain or what tree species it is. Most people just see a piece of wood, period and have a certain price they are going to pay. I'll be honest based on my experience is that if you get $50 bucks for one maple slab your doing good, if your lucky enough to find a buyer, hardly worth the effort to cut it,I know. You could get lucky and sell it for the big bucks to a wood guru with all the tools to make a nice table out of the slab , but those type of buyers are few and far between, most of them probably have access to free wood and only need to have the wood milled.
I myself have never sold a slab per say, only benches. Doesn't seem to matter how big or what style the bench or how much finish work they received they only go for $ 80 to $100, this what I based my $50 slab price on , again hardly worth the time or effort to make a bench. The prices on the internet for slabs are just unrealistic to me. If they do get those prices you can bet they have tons of storage and there is a very slow turn over.There customers are probably large corporations or companies who make these large conference tables for large corporations. If slab wood did bring in these internet prices there would be many many more people selling slabs.
I wish you luck J S 929 in your marketing and selling, going to be tough but there are always some individuals who make it to the top of heap and make the big bucks, maybe that will be you. Myself, I have never been a top of the pyramid type guy but more in the middle of the pyramid when it comes to selling things.
