Looking for ideas on the best way to "restructure" my holdings.

Hi all,

My PM holdings currently consist of a mixture of Gold Eagles (various weights), 1 oz Silver Eagles, 100 oz Englhard bars, and bags of 90% silver halves.

I'd like to simplify what I own into fewer forms; probably reduce the 100 oz bars and the 90% silver halves and increase the Silver and Gold eagles. Of course, I'm hesitant to give up the premium (on both the sell and buy side) to carry this out.

Does anybody have some good tips on how to rebalance physical holdings?

Thanks!
