Track what you own.Know what you made.Know what you owe.
Your broker tracks your stocks. Nobody tracks your cards, art, or watches. Until now.
Every asset class, every metric that matters.
Stocks are taxed at 15–20%. Your PSA 10 is taxed at 28%.
The IRS classifies graded cards, art, watches, and comic books as “collectibles.” That means a higher long-term rate, plus fees nobody tracks. We do the math you'd otherwise do in a spreadsheet.
Long-term capital gains. Your broker prints the 1099. Done in an afternoon.
Maximum long-term rate. Plus grading fees, selling fees, shipping. None of it pre-calculated anywhere.
Investment-grade infrastructure for assets that aren't stocks.

Purchase price, grading fees, shipping — every acquisition cost tracked. Holding periods computed automatically.
Tax lot manager
Short-term and long-term lots, pre-calculated and CSV-exportable the moment you need them.

AltGems tracks every major alternative asset class: TCG cards, sports cards, art prints, luxury watches, comic books, and precious metals. Sealed product is supported as a flag on cards and watches. If it appreciates and the IRS taxes it differently than stocks, we track it.
Prices are sourced from real eBay sold listings in the last 90 days. We use the median of recent sales, not the mean, to filter out outliers. Confidence levels (High/Medium/Low) tell you how many comparable sales we found.
No. AltGems calculates everything automatically: cost basis, holding periods, short vs long term treatment, and estimated tax liability. Export a Schedule D CSV when you need it.
