There is Troy's system, which we revised for the Wake of the Schism, calling it dowry.
The way I interpret it, young magi are expected to bring some kind of Gift into the covenant when they join, and their parens or alma mater would usually provide them with this. Mechanically, the players can then design their portion of covenant resources as part of character design, even if it belong to the covenant once the game starts. This expediates this part of covenant design.
The dowry is not as appropriate for an Autumn covenant as it is for a Spring one. One may still have dowry, but it would only make up a small fraction of total resources.
