Thailand year error for 1 Solot 1244 [solved]

This is from PCGS concerning converting Thai coins from the Chula Sakarat system to Gregorian. The entry in the Thai coin 1 Solot dated 1244 is 1882 Gregorian not 1883 as in catalog. 1244 + 638 = 1882.

For the first machine-struck coinage of Thailand the Chula Sakarat or Chulasakarat system was used. This was a calendar that used both lunar and solar systems to define dating. The Chula Sakarat system was derived from the Burmese calendar, which itself was derived from a Hindu calendar system. The calendar system began in 640 Common Era (CE). Due to the differences in the Common Era and the Chula Sakarat system means to get the Common Era date simply add 638 to the Chula Sakarat (CS) date. This dating system is used on Thailand machine struck coins from under King Rama III with issues being dated CS1197 (1835).
