Issue Notice:

• Colors sensitive to water, especially MiNo. 18A. Fresh colors used pieces of MiNr. 18A are therefore quite rare and correspondingly expensive.
• from MiNo. 18 there are known 2 types, which differ in the size of the "2". (Type 1 small 2, Type 2 large 2)
• Specialists also distinguish the following subtypes:
• Type I (small 2): The English "2" is at least 4 mm high
  • Sub-Type I:
    • Sub-Typ I: Well rounded "2" with prominent upstroke
    • Sub-Typ II: Right hand side of "2" flat, short food, defined upstroke
    • Sub-Typ III: As subtype I, but practically no upstroke
    • Sub-Typ IV: As subtype II, but broken at base which is rough
  • Sub-Type II: Concerns the "MAI PAT"; Occurs in both types I, II and III
    • Sub-Typ I: "MAI PAT" in a vertical position
    • Sub-Typ II: "MAI PAT" in a horizontal position
• Type II (large 2):
  • Sub-Type I: Large figure "2" which has a straight foot with a slight upstroke at the end
    • Sub-Typ I: The Siamese numeral is half way below the base of the "aw"
    • Sub-Typ II: The Siamese numeral is much lower
  • Sub-Type II: Narrow figure "2" without upstroke to foot
