FREE: Fossil Shark Teeth - Lemon, Megalodon, Sand, Tiger Tooth

I am offering free shipping so I am not quite sure what you are talking about.
Otherwise, here is your answer :

The sign is first attested in British, American, Canadian, Mexican and other Spanish American business correspondence in the 1770s, referring to the Spanish American peso, also known as "Spanish dollar" or "piece of eight" in British North America, which provided the model for the currency that the United States later adopted in 1785 and the larger coins of the new Spanish American republics, such as the Mexican peso and the Peruvian eight-real and Bolivian eight-sol coins.

The best documented explanation reveals that the sign evolved out of the Spanish and Spanish American scribal abbreviation "ps" for pesos. A study of late eighteenth- and early nineteenth-century manuscripts shows that the s gradually came to be written over the p developing a close equivalent to the "$" mark.

I hope this helps you James1016

Yes, if its a nice big one, they can be expensive.

Please notice that its a quarter next to the broken Megalodon in my picture above.

Ha ha ha - The sharks are long extinct. They are from the Pleistocene era, around 5 to 12 million years old.
