What the share card is labeling
The Certificate of Speculation, from erstwhile.io
When the daily investing game at erstwhile.io ends a run, it draws a certificate. The default subtitle is Certificate of Speculation. The picture you can save is meant to be shared without giving away the year.

How to read the lines
The body says the bearer turned $10,000 into a final amount, with the end of the start year and the end of year five, a five-year percentage, and a sentence against an S&P 500 fund. Those years appear after the reveal, on your own screen. I am not reprinting a real certificate, because that would publish a solved window.
The serial is not a print run. On 11 November 2026 the public archive showed No. 35 as today, and the page ties No. 24 to 31 October 2026. Padding that puzzle number is what produces No. 000035. I call that derived from the public numbering, not a sentence the FAQ prints.
Signatures on the card read “The Bearer” and “Market of the Past.” Styles change the look. They do not change the score. Free play uses the classic style.
Result names, without the cutoffs
The public game uses result names that run from a best-play title (Time Traveller) through a worst-play title (Perfectly Wrong) and a rock-bottom line, plus percentile bands. The exact cutoffs are not written up as a help page. I name the titles and I do not invent the percentage bands.
Questions
Can I post the picture?
The save-as-image file is described as leaving out the years, the holdings, and the S&P figure, so the picture itself is the shareable object.
Does a fancier style raise the score?
No. Styles are cosmetic, and the extra ones are a Supporter perk.
