I would looking thru the price ranges of various "common" Sharks & Rays for home aquaria both LFS & online dealers.
While I also realize that prices vary from state to state, or country to country.
Here's what I found for some of the more well know species.
Brown Banded Bamboo (Chiloscyllium punctatum) - $20-40 for egg, $50-80 for juvies.
White-spotted Bamboo (Chiloscyllium plagiosum) - about $70-100 for juveniles
California Horn (Heterodontus francisci) - ranges from $100-200 depending on location & size of juvenile.
Coral Catshark (Atelomycterus marmoratus) - usually between $90-125
Epaulette (Hemiscyllium ocellatum) - usually around $300-400, but some captive bred juveniles can be found for around $200-250.
Marbled Catshark (Atelomycterus macleayi) - usually about the same as the Coral catshark in terms of price.
Port Jackson's (Heterodontus portusjacksoni) - usually found ranging from $350 -500 each.
Gray Smooth hound (Mustelus californicus) - about $150-250.
Just a few examples to start with.
