This is Prague, 1960–2001 system. Format: A (= Prague) + BH (serial letters) + 17-30 (sequential number). White background with black text = passenger car. The ABH series is relatively early in the Prague sequence. Prague was the only district with a three-letter prefix (the first "A" was fixed, then two serial letters were cycled starting from AA onward). The exact year of issue is hard to determine from the number alone, but ABH is likely from the 1960s–70s, when Prague's series were just starting to fill up.

it seems that it's 1992
