My first suggestion would be to use MediaWiki symbols for separating multiple
inputs, e.g.
{{#display_points:points=55.7557860; 37.6176330 | 1; 1 | 12; 34 }}
This lets you use ";" as a separator between components of a pair, which will
be helpful for internationalization (Germans have an odd convention of using
"," instead of "." as a decimal separator, so your current notation looked
rather confusing to Germans).
As a next step, you could allow further named parameters after a coordinate
pair to specify more information, e.g.
{{#display_points:points=55.7557860; 37.6176330 | title=foo | 1; 1 | label=bar
| 12; 34}}
The "parameter=value" style is something users are familiar with.
