I have a small collection of about a dozen or so Costa Rican Counterstamp coins, most - if not all with counterstamp date 1923 over 18xx. 25c 50c and 1 colon denominations- all silver. I'm looking to complete my circulated liberty nickel collection. I'm in search of the 3 rare dates 1885/1886 and 1912-S (I have all other dates). I will consider "ugly duckling" coins to complete the set if the trade is fair - as long as date and marks are readable. I'm located in the Sacramento area of California.
