Gains & Drops Don't Add Up

I track the value of my collection every day or two. Sometimes I'll see that my collection has increased in value by, say, $50, without adding any comics to the database. I go see which books have changed in value and their individual changes don't add up to $50. It might add up to only $20. Why am I not seeing everything? Am I doing something incorrectly? |

Two rare occurrences that might cause this. One is that there were duplicate listings of the same comic in the system, each with a different value, and an administrator merged the two listings...your comic would have moved into that merged listing and if it didn't have the same value it wouldn't show as a value change. Two, when making a valuation change an administrator either didn't like the value the algorithm spewed out for all grades and manually changed a few, or an error was made and corrected...you would only see the change from the most recent adjustment. This is not something I would expect to see on a regular basis though, but it does happen
I don't know what's going on but it happened again. I've been checking every day and my collection increased in value by $97 today. This was the first change since 6/18. I checked the gains and drops. It showed only one value change, and that was a LOSS of $42. |

Hmmm..what issue did you show a $42 loss on? I can see if there is anything unusual there
It was X-Men 129B in grade 7.5 and the drop was actually $48 (my bad in the previous post). I use a spreadsheet to track the values so the reported increase was accurate. Thanks for any help. This has been going on for a while. |
