It's not a problem asking 100% of the retail cost if that's what you want (yes you'll end up back here but so what?), might take longer to sell the item & might drop your price a few times but you'll eventually get an offer, up to the seller if they accept it.
Not quite the same, but I did something similar, asking for roughly the new price I had paid, but I had paid a much reduced sponsor / supported price
It was genuinely hardly used due to the size of my armoury, and a specific limited edition colour/design and bagged in the original case that only came with a short original run.
Not that any value is added, but it had only been serviced by the manufacturer tech guy, and maintained by our certified team tech guy
There may have only been two in the country, and it’s the only one I had seen in the country
(I say two because my team mate had put his name down for that colour version before we were offered a team deal, but couldn’t wait and took a standard - his may have sat on the shelf or I might have actually ended up with the one earmarked for him)
I decided to sell due to the value and lack of use - I had used it once and loaned it out 2 or 3 times. However I wasn’t going to let it go cheaply as I didn’t need the money, otherwise I may as well hang on
That meant I was in the situation of asking for X but getting low ball offers, I was open to offer but not willing to drop heavily
I’d get low offers telling me that just because it’s a limited colour doesn’t mean it’s worth more (OK then - buy one of the many standard ones available), or that the colour was a little more widely available in the US (OK, go and import one then), also that there was a small rub on the barrel (OK, don’t buy it) and finally that a UK retailer was listing one from new (OK, try buying that one at full retail price - a few hundred £ more than me - until you get to the cart to be told it’s out of stock)
It did take me something like a year to sell, during which time I got a couple of ‘one last time’ games with it ….. and sold it on eBay (breaching rules) at an acceptable offer and during a promotional fees discount selling a £1400 - £1500 retail gun, (I had paid nowhere near that - probably trade price) for about £50 to £100 less than I had paid and obtained some use from it, and it sold to somebody who appreciated the mainly visual limited edition elements
A private sale can happily be made between two people for an agreed price, that one is willing to part for and the other is willing to pay
As long as one isn’t purely ripping off newbies with exaggeration then it should be fine
