Traditionally, there was never a single symbol or special character for the Spanish peseta.
Common abbreviations were "Pt", "Pta", "Pts" and "Ptas", sometimes using superior letters: "Pᵗᵃˢ".

Common earlier Spanish models of mechanical typewriters had the expression "Pts" on a single type head, as a shorthand intended to fill a single type space (Pts) in tables instead of three (P+t+s).

Later, Spanish models of IBM electric typewriters also included the same type in its repertoire.

When the first IBM PC was designed in 1980, it included a "peseta symbol" "Pts" in the ROM of the Monochrome Display Adapter (MDA) and Color Graphics Adapter (CGA) video output cards' hardware, with the code number 158.
This original character set chart later became the MS-DOS code page 437.
 Some spreadsheet software for PC under MS-DOS, as Lotus 1-2-3, employed this character as the peseta symbol in their Spanish editions.
 Subsequent international MS-DOS code pages, like code page 850 and others, deprecated this character in favour of some other national characters.

In order to guarantee the interchange with previous encodings such as code page 437, the international standard Unicode includes this character as U+20A7 PESETA SIGN in its Currency Symbols block.
Other than that, the use of the "peseta symbol" standalone is extremely rare, and has been outdated since the adoption of the euro in Spain.

In the version 1.0 of Unicode the character ₧ U+20A7 PESETA SIGN had two reference glyphs: a "Pts" ligature glyph as in IBM code page 437 and an erroneous P with stroke.
In Unicode 2.0 the reference glyph P with stroke was erroneously displayed as the only symbol for peseta and was later corrected to the Pts ligature and a separate character code was added for the peso sign.
