If you have a few other coins of similar value, the occasional ANACS special might do you well. Those tend to average around $10/coin and IMO works for a positive ROI. I agree that
NGC or
PCGS might be pushing cost prohibitive.
I took advantage of the special last Aug and submitted 20 coins. With some extras like conservation for a few and variety attribution on a few, I was all in at $300. I am certain when the time comes my family sells them, they would get more than $300 vs the value of those as raw.
