Isnt it working as ADJECTIVAL clause(clause modifying a noun) and modifying ."something" ..GMATGuruNY wrote: In the SC above, whether it is a baseball card...or a postage stamp is an adverbial clause modifying the rest of the sentence. The clause is set off by commas because it could be removed without altering the basic meaning of the sentence:
The rarer something becomes, the more avidly it is sought.
The rarer something becomes, whether it is a baseball card or a musical recording or a postage stamp, the more avidly it is sought by collectors.
The modifying clause serves as an adverb in that it indicates under what conditions the ACTIONS take place: something BECOMES RARER and IS SOUGHT whether it is a baseball card or a musical recording or a postage stamp.
