THE SHORT ANSWER
One fine ounce sets the metal reference; the transaction sets the price
The standard American Gold Buffalo bullion coin contains one fine troy ounce of 99.99% gold. Its melt reference therefore equals the source-labelled gold price per troy ounce. The $50 denomination does not cap or guarantee market value, and no retail premium or buyback bid should be invented: compare real, same-time dealer terms for the exact bullion coin.

PROGRAM BOUNDARY
Bullion, proof and the 2008 fractionals are not interchangeable
Ordinary one-ounce bullion coins move through Authorized Purchasers and retail dealers. Proofs are collector versions sold directly by the Mint with specialized finish, packaging and a certificate. The Mint also offered fractional proof and uncirculated collector pieces in 2008; that historic release did not create today's standard fractional bullion program.
