Great coins. I agree, the flip-over double strike elephant is awesome! Your almost unique civil war coin is a great find. (yes, almost unique is an oxymoron)
I do the same way. I have to sell several the real best Russian Empire silver roubles and poltina from Peter 1 times (beginning of XVIII AC) to buy my best EL / AV ancients. My choice is a gold and electrum coins and I have no any doubts with this choice.
I appreciate all the kind words. I'm saving up for a few choice targets this year, hopefully we won't be battling to hard against each other!
Personally I could care not one whit if a coin is gold, silver or base metal (though I do like bronze and brass). Coins #2, 3, and 4 exhibit some very fine selections in Roman portraiture. Very fine specimens indeed!
Nuthin' but winners!! (congrats on an amazing coin-year) ... the double-elephant is pretty hard to beat
