I have "flipped" quite a few OT Royalex boats on Craigslist and also FB Marketplace. There is a demand for these old boats, although in its current condition, yours is one that a flipper might buy to repair. It needs some work.
The abrasion of the bow and stern top layer does not appear to be through to the foam core, but if it is not repaired/dealt with, it will be soon. Once that happens the boat is no longer serviceable.
I that were my canoe, I would first repair (carefully by masking off the repair) the worn areas. I would then apply skid plates to both ends. DO NOT buy the skid plates from Old Town. Their price is absolutely insane. Look into felt skid plates (better than Kevlar) that you will apply with an epoxy. Be sure that you carefully mask and rough up the area were these are installed to make sure that they hold. Also remove any bubbles that might collect during installation. I would also buff out the rest of the hull to get it back into shape.
If you are not good at doing repairs with epoxy, you might be better off selling the canoe as is since a mess made with epoxy is one that most of us would not want to deal with.
In its current condition (presuming the rails and seats are not cracked) I would probably offer up to $350 for it and expect to sell it for about twice that once it is properly sorted. If you figure out the costs (skid plates, epoxy) there is not a lot of meat on those bones, but to someone looking for a good canoe to use, it's worth taking the time to sort it out.
