The price is every much dependent on a few things.
- How has it been used? has it been a race ski/training ski or just used for free-skiing
- How much use it is had. a slalom ski that is trained and raced regularly will naturally lose grip/rebound as it ages
- How much edge is left. A slalom ski that is being tuned regularly for race/training is going to have relatively thin edges after a couple of years which means it does not have an extended life span as it will run out of edge even if the ski has not deteriorated
- Base condition is to some extent less critical for a slalom ski, provided it has not had any edge hits to collapse the sidewall or multiple core shots
- What binding is on it - I can see it is an Xcel but is it a 12 or a 16?
A couple of other things to consider. It looks like the FIS slalom rather than the detuned one but i can't ben are from the graphics. The shape and plate positioning changed on the Augment slalom for the 2020 season which based on my experience and preference further improved the ski but the previous variant was pretty good to start with.
It is the 155 ski so less in demand and less value than the 165. The 155 slalom is now typically the preferred junior/U14/smaller women ski with competitive women on the 157/158 BUT Croc/Augment did not have a 157 in the line at that time (they do now) so the lower flex #s (5 and below) are a beefier ski than might normally be expected from a 155.
So, without some more info on the ski - specs, use, edge life, condition etc - it is hard to value. It LOOKS in decent condition from the top sheet which would suggest that it has not seen a lot of gates or hard use. So value wise and assuming it is an Xcel 16 I would personally value it at $250-$350, depending on your market demand and condition. To put this in some perspective I just sold a brand new Atomic 2020 Redster 157 FIS slalom with new X16s for $525
