Like Matlock above already mentioned it´ll mainly depend upon the way your planning to sell them. Obviously the average prices will stay lower when you plan to list them as a lot in relation to selling everything one by one but that´ll be a time spending procedure so it depends a little which way your willing to go.
I have no clue what that Terror Dome your looking for would be worth so guess you can tell yourself or someone else out here will but I´ll be able to give you a fair and realistic estimate of what you have here when it comes to your BB collection. First of all let´s start, as always, saying that condition is crucial and this will probably also go for the Terror Dome your looking for so figures in good and complete condition will be worth quite a bit more than figures with issues like paint damage, missing rubsigns, etc.
When it comes to the 57 Beasts you have the good thing is that most of them are from Serie 3 which are figures that are less common than the Series 1 and 2 so in good condition on average they´re around $10 each at least when complete with weapon. 20 are missing the rub and 2 are in less condition so it´s save to say these are around $5 each. All 15 weapons you have belong to Serie 3 Beasts but saddly not all of the figures who have a weapon still have their rubsign so that makes it a bit tougher. So before we start going into complicated and to detailled calculations I think it is pretty fair to go with an estimate of $6.5-$7 each for the 57 Beasts in which case the ones complete with weapon and rub will obviously represent most of the value. This makes a price of around $370-$400 IF you decide to take the time listing them separately this should be a realistic goal. When listed as a lot I don´t see them go over $4-$4.5 each since the average condition is to diverse for a solid average price a figure. The Orange Gorilla variant who seems to be in good condition might hit higher and the same goes for some individual Serie 3 figs like the Penguins but that´s already taken in account with the averages mentioned above because some Serie 1 figs without rub might only be worth a few bucks IF they sell.
Prices of the Vehicles and Playsets tend to vary quite a bit but for the 4 you have there $75-$100 for them would be a reasonable price to get, here it also depends on whether you decide to list them as a lot in which case you´d have to think more towards the $75 price or whether you decide to list them individual in which case the $100 might become an option in case the right bidders show up. Most important thing with the playsets in order to get a fair price is their completeness and that´s impossible to tell at the moment.
The Poster you have is the Canadian version as it is bilingual (EN/FR) and that might be worth around $35-$50 for the right buyer.
So to summarize I think its fair to say your lot as such and in this condition will be worth anywhere from $350-$550 where the higher numbers will only be an option in case you find either the right buyer or list them all one by one. At this moment I think its fair to keep in mind the market is very uncertain so to be safe even keep in mind a difference of $100 in relation to the lowest price mentioned which means it could also be $250 for all but that´s a minimim price you should fetch for sure.
Hope this helped.
