Hello!
Following this request from ... 2011, I added a rough evaluation of one's collection value based on the 2004~2022 average of selling prices on LDDb.

This is BY NO MEAN a precise statistical tool and is only here for entertainment because:
- Titles that have never sold here will not contribute to the sum => underestimation
Could come with a warning that only X% of the collection has statistics to back the estimation. - Unless the prices have remained flat since 2004, average will overestimate price drops and underestimate price increases.
Could be improved by using moving averages or "X most recent" when available. - Without grading added to your collection, the mint average prices will be used, this would underestimate collections with sealed titles and overestimate collections with used/damaged ones.
Requires user inputs. - Very mainstream titles with multiple transactions will bring some interesting contribution to the sum but collections with obscure/unique title will be grossly underestimated.
