I have a series of 25 consecutively numbered US $1 Silver Certificates, 1957 series.
Condition is crisp uncirculated.

I'm not a currency collector, so I'm seeking advice on value & how to sell (if I decide to). Is there a standard reference & value guide for US currency? If I sell, is there a premium value placed on selling all 25 with concecutive numbers (vs. selling individually). What's the best venue for selling for max. value -- local coin shop; coin show; ebay; etc?

If you have a currency reference book handy, what's the value estimate for these Silver Certificates?

You can respond here on the BB or in a private email. thanks.
