It depends on the condition and denomination.
For most denominations, perhaps 5 to 50 US cents in circulated condition and 75 US cents to 1 US dollar in Uncirculated condition. For the 50 cent piece, perhaps US$1 to US$5 in circulated condition, and perhaps US$10 to US$20 in Uncirculated condition.
In terms of foreign exchange value (and I'm not certain whether 1965 coins still circulate), the exchange rate would be EC$2.70=US$1.00.
