"Business strikes" yes.....Lincolns that are copper in the sets yes....
But I was meaning the totality of ALL the coins in the set....the one year only designs ..or last year of a series...or a new first year design.
The Sacagawea's. ...Territory qtrs...Lincolns...All the coins. There was alot happening in that set simotaneously!
But, as was said earlier, if no one really cares, and everyone who wanted one purchased 8 Sets....the demand for the Set (and any other set produced) will remain at ZERO...

If you coveted the new design change of the Sacagawea, you bought P&D roll sets from the Mint.
If you coveted the Copper Lincolns, you got them SEVERAL different ways from the Mint.
If you coveted the Territory Qtrs., you got those P&D rolls from the Mint.
But the "Set" had them ALL....as far as Sets go, I just sure thought it would hold a value better than most.
But it's too watered down and devalued by the Mint itself with so many individual product options, I guess too.
