Just a note on the dates on these coins. For many years, Thailand issued coins with "frozen dates": the date on the coin was the same, no matter what year it was actually issued in; there is no way to tell the actual year of issue on the coins, though there are varieties that can narrow down the date range.
25 satang coins dated 2500 were issued from 1957 to 1987.
1 baht coins dated 2505 were issued from 1962 to 1982.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
