I would prefer to sell them as one large lot for $90 including US shipping. Due to the weight overseas shipping would be too expensive I think but if you want to pay for it I don't care.
Otherwise see below for the price per coin, according to the date range. The shipping will be $6 whether you buy 10 coins or 100. If nobody buys the whole lot by Friday evening then they will be sold per coin on a first come first served basis. (hint, the 1800s coins go quickly and are limited)
Please don't confuse these with the "unsearched" coins sold by the pound* on eBay which are invariably comprised of the contents of a Mexican roadsweeper's cart and a lot of worthless pocket change. While there are some slicks and culls there's a lot of numismatically interesting coins too and only a small handful which are less than 60 years old. There may be some duplicates.
Lot 1. Coins from the 1800s. Some silver but not enough to get excited about. 30c per coin. 40 available
Lot 2. Coins from the 1900s and 1910s. 25c per coin 58 available
Lot 3. Coins from the 20s and 30s 20c per coin. 143 available
Lot 4. Coins from the 30s and 40s. 15c per coin. 282 available.
Lot 5. 1960 onwards. 10c per coin. 42 available.
* Long ago I used to sell surplus coins by the pound ($20 per pound for vintage coins) until the day some arsebag complained that the weight was short. I knew it wasn't because they were carefully weighed out on a very accurate ex USPS scale which I've had for years and then a handful of extra coins added just to be sure. During subsequent conversations I found that the guy didn't even posses a rudimentary kitchen scale. He weighed himself on the bathroom scale, then put the coins in his pockets and weighed himself again. Life's too short to be dealing with idiots like that so I've never sold coins by weight since that day.
