"Fluffy Bun" worth: Priceless. A capstone to the gate barring distractions, misery, and mayhem from any dark side of life.
"Monetary" worth: What someone will pay...long after I'm gone. It's all recorded/inventoried in an Excel tome. Included are two columns for nearly every item, labeled "Paid" and "Value", the latter of which is a mix of MSRP and secondary market sales data, including mo/yr. If it was a kit-build or scratch-build by myself, the value is pretty much the same as I paid for the kit/materials..no one ever pays for what your time on earth is really worth when you're having this much fun, do they?!
None of which matters to me while I'm still here.
Besides, my wife is into the hobby. She should survive me by about 20 years, comparing family histories and genetics. In the longest run, it's her call.
