Acetone would have safely removed the glue residue along with any other organic matter. Acetone is non-reactive to silver. It would not have "polished" the coin.
I don't shine mine. I used to until I found that reduced to value to basically melt. Some may say that it's just a 1923 Peace dollar and only worth melt in that condition. A few years ago I would have heartily agreed. But there are varieties of the 1923 that collectors pay around $800 for XF. Fortunately this is not that variety, but there are many that base value on the date and mintmark alone. This could prove to be a costly assumption. I acquired an XF 1878 Morgan dollar a few years back and paid the XF price (around $40). It turned out to be one of the rarest die varieties and was worth $4000 in XF. I collect these varieties and so many have had their value cut drastically by a previous owner with an urge to see a shine.
Maverick you're free to do whatever you want with your coins ... they're yours to do with as you please. But I would be remiss if I didn't mention this. Knowledge is $$$$.
