We compare the seller's asking price with the market median of comparable plates in our catalog. Every figure is an asking price, not a transaction price.
This price is based on a listing on newtabien.com, listed at ฿199,000. Last checked 11 Oct 2026.
Compared with 2 plates in the group Number 5155 Bangkok all series (series-adjusted)
Actual asking prices of the 2 plates in this group (before series adjustment, and not including this plate): ฿55,000 to ฿159,000
This median lies outside the prices sellers actually ask in the group (฿55,000 to ฿159,000), because it is adjusted to this plate's series, which the group does not include. Treat it as an estimate beyond the data.
There are not many plates in this group in our catalog yet, so this figure is a rough guide to help you decide. We cannot yet say whether the price is cheap or expensive, and it is not a transaction price.
This market median is already adjusted for the series and the plate's digit-sum grade. The group contains plates from several series, and the median before adjustment was ฿107,000. The market prices the series กก higher than ordinary plates in the group, so the median was raised to ฿237,000.

A number texts advise avoiding, because life tends to be bumpy and unsettled.
Digit sum 18 blends the Sun and Rahu, giving a rhythm that shoots up fast and falls just as fast. Owners of this number often get big opportunities but struggle to hold on to them, and tend to get involved with people who are not straightforward. If you must use it, avoid acting as a guarantor, investments promising unusually high returns, and big decisions made in a hurry.

Adding the digits again until one digit is left gives 9, which some schools use as extra reference. This site grades the plate on the full sum, 18.
| Pair | Grade | Meaning |
|---|---|---|
| 51 | Excellent | A pair of protective prestige, joining virtue with dignity. Texts regard it as the pair of people backed by powerful figures and given roles caring for others. |
| 15 | Excellent | A leader backed by seniors. A popularity pair much loved by Thai people, bringing both credibility and opportunities that come without asking. |
| 55 | Excellent | Jupiter with Jupiter, giving twice the credibility and kindness. Texts regard it as a highly auspicious pair that brings support, wisdom and helpers at every stage of life. |
The texts give the last pair more weight than the others, because it is the end point of the number.

Chinese belief reads numbers by what they sound like and gives the last digit the most weight, as the end point of the number. This plate scores 51 out of 100 on the Chinese side.
No combination from the Chinese texts this site uses was found, so the Chinese score mainly comes from the meaning of each digit.
According to Flying Star feng shui, Period 9 runs from 2024 to 2043, and the digits 9, 1 and 8 are considered the lucky stars of this period. The system therefore adds a few points when the last digit is one of these three. This is an interpretation based on the star periods, not a fixed rule, and it may change when the next period begins.
The last digit of this plate is not a lucky digit of Period 9, so there are no points for this part.
