Seems vinty goes for uber coin in the UK lately, more than anyother place that I have seen.
I noticed an auction that went for $1,517.67 for 95 figures including 16 of the last 17. It was missing Yak Face.95 Vintage figures complete incl 16 of last 17!!
Like I mentioned, having repro weapons will decrease the value & if some of those weapons are with the last 17 then...
I have no idea which figures you have that repro's, hopefully lower end fig's.
You should do well with a complete description & mentioning the repros, $400. plus was just a guess but you could get $1000. plus depending on the bids.
As selling as a lot or individual, your choice. Some are looking to buy in lots & be done with it & others are just looking for singles. You could sell the last 17 as a group or the others a separate group or all togther. A reserve will protect the sale just incase.
