dates on coins

I've found the earliest imperial coins that can be designated to 1 year, see below. Tiberius.

I'm not an expert on Greek and Republican, but I know Republican denarii exist with a specific sign (a small symbol stamp) for each year.

Ok, Roman imperial. let's have a timeline of imperial Roman titles.. well documented dates..

23 B.C. - Augustus: TR.P. for life

20 B.C. - Augustus: IMP.4

15 B.C. - Augustus: IMP.5

13 B.C. - Augustus: COS.11,

**- Tiberius: COS.1 **

12 B.C. - Augustus: IMP.11; PONT.MAX.

- Tiberius: IMP

11 B.C. - Augustus: IMP.12

8 B.C. - Augustus: IMP .14

- Tiberius: IMP.2

**7 B.C. - Tiberius: COS.2 **

**6 B.C. - Tiberius: TR.P. **

5 B.C. - Tiberius: TR.P.-TR.P.2

4 B.C. - Tiberius: TR.P.2-3

1 B.C. - Tiberius: TR.P.5 expires, is not renewed

4 A.D. - Tiberius: TR.P.6

5 A.D. - Tiberius: TR.P.6-7; IMP.3 In the year 13BC prince (caesar) Tiberius, the son of Augustus, aquired the title COS I, designated Consul for the first time. Now Tiberius coins that show COS I were struck between summer 13BC and summer 7BC.

The earliest

*single year* we can find in above timeline is

**6 B.C. - Tiberius: TR.P. **

5 B.C. - Tiberius: TR.P.-TR.P.2 Find a coin with Tiberius TRP (and

*not* TRPP or TRP II

) it can be dated between Juli 6BC and Juli 5BC.
