No, it literally, as in literally literally, talks about how they don't value possessions based on their monetary value.
"As do many other races, halflings enjoy accumulating personal possessions. But unlike with most other races, a halfling’s idea of value has little if anything to do with monetary concerns. A typical halfling’s most prized possessions are those that have the most interesting stories attached to them."
To break this down.
Halflings enjoy accumulating possessions "BUT" (by using But, a conjuction [an uninflected linguistic form that joins together sentences, clauses, phrases, or words] they are explicitly tying this new sentence to the old sentence)
Unlike other races (who accumulate personal possessions) a halflings idea of value (for their possessions) has little to do with money. Now, this is where you stop, and say " AHA! They don't like money, they wouldn't take payment for work in Money! Because they don't value it!" However, this is still EXPLICITLY tied to the idea of possessions. And the following sentence clarifies, by telling us that the POSSESSIONS a halfling values have the most interesting story.
This is explicit and literally referring back to the idea of monetary value in that sentence. Not because halflings don't use money and don't want to be paid in money, a thing that is mentioned nowhere in these three sentences. It is all tied into their possessions. They aren't going to value an expensive dress just because it is expensive. They aren't going to value expensive dishes because they are expensive. Their most valuable possessions are valuable because of sentiment.
But, if you try and pay a halfling through "the expeirence of working for me" I'm sure they are going to insulted, just like most people would be. Because they do use money. And they still believe money has value. They just don't like possessions for their monetary value.
