Dating

The absence of further stampings (grade, shape or numbering) is unusual in the more recent productions, but it is found on some pieces from the initial production and the early maturity of Ser Jacopo.

Additionally:

- the "J" logo on the stem is consistent with production after the abandonment of the coral dot;
- the font of the Ser Jacopo signature and the PER ASPERA AD ASTRA stamp are compatible with 1990s production;
- the rustic finish is typical of the period in which Giancarlo Guidi consolidated the workshop’s style.
My estimate

I deem it likely that your pipe was made between 1995 and 2002, with higher probability for the 1996–2000 period.
I wouldn’t date it beyond 2005, because in later productions it is more common to find additional stampings (shape, grade, etc.).
Value

The estimated €200–€250 is consistent with the photographs and with its condition.
If you sold it at a specialized auction dedicated exclusively to pipes (for example with dealers or collectors in the field), it could reach €250–€300, especially if accompanied by original case or documentation.
Conclusion

The dating I consider most plausible is:

1996–2000 (with a reasonable margin of ±2-3 years).

It is a Ser Jacopo from the first mature production, well preserved and representative of the classic style of the Pesaro workshop. It is not a rare series identifiable by a specific stamp, but it remains a good artisan piece with collectible value.
