A Solid Serial Number: What Is It?
In a solid serial number, the same digit appears twice. For instance, 77777777 or 55555555. Solid serial numbers on banknotes can add significant value because they are quite rare.

The near solid serial number is a variant of the solid serial number. This variety is less useful and more frequent.
VALUE
Regardless of condition, a good serial number bill will always be worth more than its face value. Uncirculated bills will fetch the highest price on the market.
The majority of uncirculated solid serial number notes are valued at more over $400.
All-9 solid serial number banknotes are considerably rarer and can fetch higher prices on the market. This is due to the fact that not all series have print runs of more than 99,000,000.
Asian collectors are willing to pay extra for well-maintained bills with all eights on the serial number. In Asian culture, eight is considered a lucky number.
Regarding banknotes that are collectible, the phrase “solid serial” refers to a note’s serial number that has all of the same digits.
A banknote bearing the serial number 888888 or 777777, for instance, would be regarded as a solid serial note.
The solid serial number just denotes the numbers that come after the prefix; it need not contain the prefix (AH/01, for example).
Solid serial numbers have a “cool factor” and are extremely rare compared to regular notes, which makes collectors highly appreciate them.
A Solid Serial Number Banknote: How Rare Is It?
The amount of digits in the serial number determines the precise rarity of each solid serial number note.
The majority of Australian banknotes in circulation up until 2016 had six digits in their serial number, meaning that one million notes were issued with each prefix.
A print run of any single prefix may have up to nine consecutive solid serial numbers for notes like that: 111111, 222222, 333333, 444444, 555555, 666666, 777777, 888888, and 999999.
This implies that the maximum number of notes with a solid serial number in every print run will be 0.0009%. There are nine notes in a million, or 111,111 to 1.
Compared to normal notes, that is an exponential increase in rarity from which a good serial is obtained!
Australian banknotes from the NGB series are 10 times rarer than notes printed before to 2016. This is because each serial number on notes issued under the NGB series from 2016 onwards consists of seven digits.
A staggering ratio of 1,111,111 to 1 may be found in 9 notes out of 10 million.
The rarity of banknotes relative to regular notes increases when we consider that many print runs do not reach the full million in each prefix.
It is almost unbelievable how readily available notes are to collectors in any condition years or decades after they were first issued, especially when we take into account that the majority of the notes in every print run are used, withdrawn, and destroyed.
The goal of collecting solid number notes is to acquire them in mint or uncirculated form since, as every banknote collector knows, such notes are far rarer and consequently more expensive than the same note in circulated condition.
For the whole of their careers, many collectors may not see or purchase a single solid serial number note in any condition, much less one that is in flawless “mint” condition.
