Below which price is an offer for Iron Boulder ex SVP Black Star Promos 147/225 unrealistic?

lastsold uses only real sales — eBay plus auction houses like Goldin & Fanatics — recent sales count more (recency weighting), outliers and fakes are removed. It's not an estimate but actual sold prices, separated by condition, language and grading.
