How Luxury Sellers Use ALT/FNDATA

🔍

Value Before You List

Now I know what my piece is actually worth — evidence, not hope.

Find out what your piece is really worth using recent comparable sales, not wishful asking prices. Set a reserve and an estimate you can defend to a buyer or an auction house.

  • Comparable sales for your exact model
  • Realized prices, not asking prices
  • Set defensible reserves and estimates
  • Condition and provenance context

  • Price trend for your category over time
  • Seasonal patterns in demand
  • Momentum signals before the market turns
  • Record results that set the ceiling
