Thanks for the tips. My LCS does not care about a premium for any special bullion coins. I have interesting bullion silver coins that are Proof and low mintage. The LCS will pay only as much as for a generic round silver coin.
Even Perth Mint or even Pandas, the LCS sells at a premium but doesn't pay anything over their generic round pay price.
Some lcs dealers can be W**kers. Guess greed plays a big role there
