If your canoe doesn't appear to fit the details of the build record then the number is wrong and I (or one of the other volunteers) could search for the correct one. Sometimes taking a digital picture of the number will bring out more detail. Post the picture here and many eyes can help decipher the numbers, if necessary. Is it a square stern boat (rather than a canoe that is pointy at both ends)? Is the trim mahogany? Does it have a long, 4 foot deck, or the traditional Old Town short deck? Canoes don't seem to travel much from their original destination, even after many decades--- so, does the location where it was shipped seem reasonable or halfway across the country from where you knew it lived? A 1946 boat or canoe would have been built during a period of wartime shortages, before Old Town was able to get brass fasteners for use in the building process. Boats built from 1943-1947 are sometimes referred to as "war time boats", even though WWII was over by 1946. Such boats have a place in history but don't hold together as well as a boat fastened with brass and copper.
In figuring out what your boat should be insured for, don't look at the prices people are asking on eBay these days.
My homeowners' insurance policy would only cover a canoe worth $300. Unless your boat needs lots of work, it may be worth more than that. If you had it restored to perfection and paid $3000 for the restoration, then insure it for at least that amount. I'm not saying that's what you could sell it for, but to you it is worth that. But I'm assuming that by "very good condition" you mean it's water-worthy and looks nice, so it might be sale-able for a thousand dollars or more, and should be insured for that.
I had my canoes insured by Haggerty (
https://www.hagerty.com/Insurance/Classic-Boat-Insurance). There may be other companies that insure classic boats, but this is the one I used. They insure a boat based on the degree to which it has been restored, which worked well for me when I had a number of classic canoes but were unrestored. So a canoe that "needed everything" might be insured for $300-- and maybe more depending on rarity and desirability. It's been my experience that there isn't as much demand for the square stern canoes as there is for those with the double ends. The value you put on the boat is up to you. Read through the information in the link I provided earlier and if you still need help figuring this out, post pictures. We love pictures of boats.
