Collection overview.

Prices are TCGplayer market benchmarks supplied by TCGdex, not guaranteed resale values or condition-adjusted appraisals. Card details show the printing, source and price date. Missing, unsupported, stale (over 7 days) and graded valuations are excluded, never treated as zero. No graded pricing provider is connected.

Account observations are recorded daily in UTC and appear automatically after synchronization. Guest data stays on this device; it cannot be recorded by the server. Guest users can refresh prices and save a snapshot manually. Daily observations do not provide intraday tracking.

Charts connect only genuinely dated observations with comparable holdings and priced coverage. Changes to holdings or coverage start a new comparable segment. The priced portion is identified when coverage is incomplete.

Market changes require fully priced observations on the relevant recorded days. They compare the prices of overlapping copies only, using the smaller quantity held at both dates; additions, removals and reclassified printings are excluded. Percentages use the previous value of those overlapping copies. Card movers compare supported per-copy prices independently of quantity. No purchase costs, cash flows or investment returns are inferred. Repeated cached prices without a new source date do not create performance.
