I would really appreciate your help in identifying this coin! The diameter is up to 21mm and it is/contains silver.
Side 1:
- portrait facing right (at least that's what I see) of a person with long hair and a laurel wreath
- letters A G • H • R (E)" [on the left side on photo] and "(L) D V" [on the bottom right], in brackets are those I am not sure about
- the number 3 in what looks like (the top of) a heart shape [bottom left on the photos, just above the hole]


Side 2:
- coat of arms
- letters: R CHI • D • (A/R)


Let me know if you'd like more photos. Unfortunately, I do not have scales to weigh the coin.
Thank you and I am really looking forward to your guesses!
