Swamperbob, I can assure you that for the price of 6 dollars each, it's absurdly cheap. I would buy almost all at once unless they are horribly damaged. If I am not mistaken, all denomination of 1795 MM kopeks are exceeding rare and if you can find them, that will be great as most of them are easily in the high hundreds if not thousands of dollars. 1789 MM 5 kopek is another rarity. Most overstrikes these days are starting to command a prenieum as there are some coins that can only be found cheaply as overstrikes such as this one:

Overstruck on a 1724 kopek which is VERY scarce.
Some of the rarer kopeks include this overstruck Swedish 1 ore which is rarely offered for sale

However, most of the common overstrikes are usually this:
2 kopeks over 1762 4 kopeks
or this

1793 EM 5 kopeks over 1796 10 kopeks
I would be interested in those lots if you have the time and I'll willing to give a hand too. Of course that's just a short list of what I have mentioned. Also, do hoard all the 1763-1767CM 5 kopeks if you can - there is a research going on to prove whether there are any overstrikes.
I wish I had more time to do something about the overstrike page that I kept talking about.
