Expected cost of a Pink Chip

[jar]

When playing at the Trop, a friend payed someone at the table $3 for a $2.50 pink chip as a souvenir of the legendary pink chip game, which is currently on hiatus.

This got me to wondering, what is the expected value of playing BS $5 blackjack until one wins a pink chip? I'm not sure the BJ rules at the trop, but I assume they're pretty bad, since it's AC. Anyone know where to find blackjack rules for variuos casinos online?
