I was thinking…how much gold do you think your collection is worth if you liquidated it? Speaking only to cageable pets + duplicates.
Tbh…it would probably take a couple hours to actually figure out what my collection is worth. But if I had to guess an estimate, I’d say I could sell my collection for like 2 million gold.
Of course, I think pets are priceless 
but it’s interesting to think about how much one’s collection is actually “worth”.
You could estimate it more quickly with the help of Magpie.
and choose “Sell Owned Pets” and optionally “Duplicates Only”.
Of course, actually selling pets is a difficult business, since the pet market is so slow and so irrational.
Oh okay cool, never knew about that! And yeah, it would take several months to actually sell pets unless you price them under market value, and even then.
A lot. Like 25 or 30 million wouldn’t surprise me. (if I sold the whole collection, not just duplicates.)
Sadly magpie doesn’t seem to show totals and the number of pets I’d be selling make it -really- tedious to attempt to figure out manually.
In my server, with 4 pets already have 2M gold…
I had this site saved in my favorites. Found the value of your collection including duplicates: https://wow-pets.com/character/us/emerald-dream/grandmamama
General rule is that what sellers are asking is totally irrelevant. Important thing is what people are paying, if they’re buying at all.
What my collection is worth isn’t the same as my collections worth.
And what I paid for it isn’t the same as what it costed me.
10,052,627 according to this site.
No idea on this site, it’s giving all the possible numbers but not tallying it up - I’m not doing that math 
but one pet at the top has a number of 759,989,99, so I’d guess several million total for all.
I have zero plans to sell my pets, except those that are spread out across 4 full bank tabs that are all duplicates of duplicates.
That site seems to be out-of-date. I’m seeing pet completion percentages over 100% and it can’t find any names of any pets.
Edit: That’s why, the site hasn’t been updated since March 2022.
