Dipped Indian Head Pennies

I went to the local coin show today. Actually, the coin show moved out of a community center, and moved into a room at the casino/dog track, and its a bigger and better show now, probably because of the additional space. Anyways: the subject is cleaned and dipped coins. A dealer had bought a collection from somebody. In the box of coins was a cleaned later date Indian Head penny. red and shiny. $130 written on the cardboard holder. The dealer said its an example of a cleaned coin, and he'll sell it for the first $20 that comes along. $20 is a big discount off of $130. I want your opinions: generally, how much of a decline in price would you expect for a BU Indian head that shows signs of being dipped. I have some beautiful coins: 1860 IHC; 1862 IHC, and a 1892 IHC; all three might be dipped. I cant tell for certain. The 1860 and and 1892 were bought from the same dealer for a combined total of $270. BU detail. if they are dipped, what is fair price? the 1892 shows signs that its starting to re-tone. but its showing a normal brown re-toning. not weird funky purplish toning like some dips cause. theres no weird brown spotting. the 1860 and 1862 are weird dates; while those also might be toned, its a different patina. Those early years were minted with a lower copper percentage. they're referred to by some as the white cents, because of the lack of a red copper color. reminder: my question is what value would you place on $270 worth of BU coins that show signs of being dipped. do you think cleaned morgans hold their value better than cleaned IHC coins?
