Cataloging The Collection?

At one time, a long, long time ago, I started an Excel spread sheet with about the same info as Sap's list. However, over time I started to delete one item at a time. And also, since many items were given to me by my Dad, again, along time ago, most of the info would be a guess. I never sell coins and at my age, possibly to late to start selling now so many other mentions of prices becomes unnecessary to me. And once any collection grows to virtually many thousands of coins, such records becomes massive and time consuming.
Once a person gets older, their interests usually becomes more of how to spend what time is left, rather than making a list for someone else. The main purpose of such a detailed list of course is

I obviously use Numismetrica to keep track of my own collection (when you develop something, you tend to use it... a lot :-) ) but even though I already have an established database schema, I find myself tinkering with it here and there, adding new fields and trimming old ones. The current schema is rather complex with 16 separate tables and hundreds of fields (not that the end user *ever* has to manage them manually as a lot of those have to do with things like price guides, coin demographics, bullion data and social media functions). What the end user plays with is point and click and tracks everything automatically.

Everything on my personal account is primarily broken down by album or container (for my CRH stuff :-) ) with call numbers so I know the place to look if I need to dig something out. I tend to be a bit of a pedant with that, but as a trained librarian it kinda comes with the calling. :-)

I'm also keeping track of my kids' collections on it, too. They love being able to watch their stats and the silver prices and FMV go up and down as it gives them a sense of accomplishment.
