Dating

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

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

I consider it likely that your pipe was made between 1995 and 2002, with a higher probability for the period 1996–2000.
I would not 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 the condition.
If I 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-based workshop. It is not a rare series identifiable by a specific stamp, but remains a good artisanal specimen with collectible value.
