It means purple. Obviously, it refers to the old version of 100 baht (version 88).
On the second floor are the 2005 commemorative tickets to commemorate the 0/00th anniversary of the abolition of slavery in Thailand.
Look at this photo for yourself. The first one is the old version. Pay attention to the difference between the signature and the back of the ordinary ticket on the left (version 04) and the commemorative ticket on the right in 2005.
04 version, formerly known as 94 version, the main pattern is similar, but the details are different, anti-counterfeiting and signature, so I won't post it here?
These materials as commemorative banknotes were provided by friends in Tibetan areas. There are many forms of commemorative banknotes, some are clearly marked, some look at the specific crown, some look at the date and so on. For example, the current $2 bill can be called a commemorative bill. Different from other denominations, it uses a picture of signing the declaration of independence on the back. Of course, the most authentic version is the first edition 1976.
The information collected on the website of the central bank is pediatrics. For example, friends who collect three editions of coins know that they are printed with intaglio, relief and offset printing. These banks won't talk. Back to the Thai banking network, there is no mention of such important information as different signature versions. Just like the signature of 100, there are three kinds now.
The main problem is simple, but everyone stands from different angles. At the beginning, I made a serious mistake, that is, I took the 88th edition of 500 as 100, because the previous one of these bills was 50, and I made a mistake for a while. You didn't correct such obvious mistakes and omissions, which made others see a joke.
Since you will go to the Bank of Thailand, you can say from the beginning that the tickets for King Rama IX are all red except for the 46-year version of 100. As long as the picture is posted at a glance, I don't have to fall into the word "purple"
