Tell you what, you probably would have best off buying BU rolls of cents from the bank. Even the 1856 FE cent would have cost 600 BU IHC's.
I read in a book a while back that average pay for a soldier in the Civil war was $5 a month. This was considered low pay at the time, but they lived on it. Not sure what average pay was for other people but if it was $20 a month, it wouldn't be too easy to drop $8 on a coin at that time. No different than spending a full 2 week's pay check on a coin today.
If you had $100 back in 1870 to drop on coins, you were definitely in the top 1%. Most people could make ends meet with $100 in a whole year back then.
