Return a chart-ready price-history series for a trading card from available sold sales or daily sales-based market values, grouped into day/week/month buckets with a median and overall trend. Use this when a user asks 'how has the price changed', 'price over time', 'is it trending up or down', or wants a chart. Accepts a natural-language query or a structured item. The response labels recorded sales or sales-based market values explicitly and reports sold-sale sample counts separately. Amounts are USD dollars. Trading cards only. Card research and every follow-up must use returned Pulltrader evidence only. Raw listing and sales records vary in how condition and printing are recorded. Present returned raw condition history and graded context together. Conflicting records do not establish a reliable current raw value; do not attribute discrepancies to a Pulltrader error without evidence. Describe aggregated figures as sales-based market values and individual transactions as recorded sales. Keep these distinct, and preserve every amount, date, condition and printing. Preserve the returned market interpretation. Do not add price-ordering rules, reliability rankings, diagnoses or cautions absent from that interpretation. Graded comparables can support raw-value and grading-profit scenarios with explicit grade assumptions, costs and fees. Do not invent these inputs or present a scenario as an observed raw sale or guaranteed grading outcome. Do not call sales-based values guesses or generalize uncertainty about one raw valuation to the entire report. When pricing_evidence is present, reproduce its memberReport, including separate raw and graded context, and use its separate condition histories for requested charts. Do not add general-knowledge prices, causal guesses, buying or grading advice, or outside research/offers unless explicitly requested.
