The ICG holder may not help increase the value of the coin. I avoid coins graded by this service as most of the coins I've seen tend to be over graded.
As for their designation of "Flat Strike," I don't know what that means. I thought all coins were flat strikes. I would much rather see "Low Pressure" or "Adjustment" strike on the label for this coin.
I did a "sold" listing search of ebay and couldn't find any listings for "Flat Strike," but you may want to check the "sold" listings for "Low Pressure Strike," "Adjustment Strike" or "Test Strike." It may give you an idea of what other coins have sold for.
