currently in Numista catalog for Cyprus coinage from 1983 to 2004 we have the following consolidated coin types:


And this division is rather frivolous and does not reflect the major coin design changes which exist.
I would suggest splitting the above coin types into the following:
1 Cent:

1 Cent (Type 1 coat of arms; single line value number)
1983
1 Cent (Type 1 coat of arms; double line value number)
1985-1990
1 Cent (Type 2 coat of arms)
1991-2004
2 Cents:

2 Cents (Type 1 coat of arms; single line value number)
1983
2 Cents (Type 1 coat of arms; double line value number)
1985-1990
2 Cents (Type 2 coat of arms)
1991-2004
5 Cents:

5 Cents (Type 1 coat of arms; single line value number)
1983
5 Cents (Type 1 coat of arms; double line value number)
1985-1990
5 Cents (Type 2 coat of arms)
1991-2004
10 Cents:

10 Cents (Type 1 coat of arms; single line value number)
1983
10 Cents (Type 1 coat of arms; double line value number)
1985-1990
10 Cents (Type 2 coat of arms)
1991-2004
20 Cents:

20 Cents (single line value number)
1983
20 Cents (double line value number)
1985-1988
20 Cents:

20 Cents (Type 1 coat of arms)
1989-1990
20 Cents (Type 2 coat of arms)
1991-2004
This new splitting will be more flexible for both coin type collectors and date collectors and everyone will benefit from it as it would reflect the existing Cyprus coinage designs more accurately.
