Priceless
These items were obviously priceless. They must have had a lot of value to Toddrick's grandfather for him to keep them hidden underneath the house for so many years! They assumed that most, if not all, of these things, belonged to Toddrick's great-grandfather and were tucked away for safe-keeping.
Definitely Grandpa
Toddrick went back to the note and had to laugh. His grandfather would leave a terrifying note on top of something this incredible! Some of these items had some monetary value, but most of them were important to the family.
