Should I Sell Coin Collection At Spot?

I was gifted these silver and gold pieces over time, and I'm considering selling them now, as it's a good time for me personally. My collection is from Provident Metals, and includes .999 silver rounds, a 10 Troy oz silver bar, and a small 1/10 oz gold round.

Would selling around spot pricing be a fair deal, or should I aim for a premium on any of these? I am assuming they are not as collectible since not government issued, but would appreciate any advice from those more experienced in selling bullion. Thank you.
