I have 40 (20 oz in total) of 1/2 oz .999 silver Australian Shark Series coins (20 Great White & 20 Hammerhead). My top 2 LCS were at $280 cash or $300 trade-in value. I was looking to trade-in the silver for 1 oz silver rounds, which can net me 19 rounds (19 oz). Or do 90% halves at $24 FV (48 halves - mostly 64' Kennedy). So to trade or not to trade? I've tried selling locally via CLs, and I don't really want to go through eBay. There isn't really a market for these APMEX shark series coins. I bought them b/c I got them for spot price two years ago. The halves would equal 17.3614 oz of silver and the rounds would give me 19 oz even but I have 20 oz in total. Just wanted to get people's opinions and takes on it. Thx!
