Short answer: no, Vinted does not show you sold prices - not on the item, not in search, not in any history page. When something sells, the listing is removed. That is why the one number you actually need for pricing is the one number the site never publishes.
On eBay you can tick "sold items" and see what things really went for. Resellers coming to Vinted look for the same tick box and there isn't one. Asking prices are everywhere; selling prices are nowhere, so pricing a wardrobe means guessing against what other sellers hope to get, which is not the same number and is usually higher.
A sold price can be recovered by watching. Take one narrow search, record every live listing, and check it again on a schedule. A listing that was there yesterday and is gone today has almost certainly sold - and the last price it carried is the closest thing to a sold comp Vinted will give you.
The limit is in that word "almost". A seller can delete a listing, let it expire, or edit it out of your search band, and from outside those look exactly like a sale. Anyone claiming certain sold prices for Vinted is overstating it. What honest observation gives you is a likely sale with a real last price, a real number of days listed, and the brand, size and condition it sold at - which is enough to price stock, and not enough to call it gospel.
Vinted
Sold Comps is that method, packaged. You give it one narrow search and a
country site; it snapshots the live listings on a schedule, and when a
listing has been missing for two consecutive runs it emits a
likely_sold event carrying lastPriceCents,
daysListed, brand, size and condition.
Three things worth knowing before you start, because they decide whether the numbers are any good:
It runs on 23 Vinted country sites, and it never records who the seller was - no seller names, IDs or profiles, by construction rather than by filtering.
