Just picked up 4 2017 silver Briitannias for $20 each. I don't ever really purchase Kooks, Lunars, Pandas, Koalas, Libertads, Britannias, Elephants and Noah's Arks b/c of the online premiums and my local shops never have them in stock nor trade-ins. But with silver at $18.45 an oz I figured it was a good deal. I'm more of a 90%, ASE, Maple, Kangaroo and Philharmonic stacker. I don't really know if the shop will get more Britannias. I like filling tubes of a particular coin instead of having some loose ones. I'm a bit OCD when it comes to that.
90%, ASE's, Rounds. That's all I stack when it comes to silver. I did buy some Canadian Maple Supermans last year but got rid of them.
