Sure, let’s treat those Pac‑Man coins like any other collectible. First, list every coin you’ve got, noting serial numbers, condition, and the exact machine model – that’s your raw data. Next, run a simple regression on historical sales of vintage arcade coins – you’ll get an expected return and volatility. Then, use a variance‑covariance matrix to see how your coin’s value correlates with other vintage items. After that, weight it in a small allocation of “nostalgia assets” versus more liquid securities, so you keep a margin of safety. Don’t forget to re‑balance quarterly and keep the spreadsheets color‑coded: green for stable, red for risk‑hot. If you keep a post‑it for every market shock, you’ll never miss a trend. Good luck, and try not to forget a snack while you crunch those numbers.

Thanks for the pep talk, but I’ll keep the snack bar in the back of the spreadsheet. If those quarters start giving you dividends, I’ll file it under “unexpected returns” and remember to eat before the next calculation. Good luck to you too.
